Christianity does not oppress women. It treats women as having the same value as men in the eyes of God, and having just as much responsibility and accountability as men. This does not mean that some televangelist somewhere isn't a jerk, or that some small-town preacher isn't only reading Bible verses that tell women to behave in some particular way, only that the faith itself and its scriptures in their entirety and in-context do not teach the oppression of women.
unless, of course, you were pretending that not treating men and women as interchangeable gears in a machine is equivalent to "oppressing" women; Christianity does indeed teach that men and women are different and have different roles, but it does not teach that women are the property of men as Islam does, or that the word of a woman is equal to one forth of the word of a man in legal proceedings as Islam does, etc. Husbands are not wives and wives are not husbands. Mothers are not fathers and fathers are not mothers. If you don't like those basic biological facts, then your argument is with reality.
Oh yeah, equal value. It just happens that women are notably absent from historical church leaders, and not permitted to be priests in the largest denominations. It's one thing to have different roles that are complimentary. It's quite another to simply say only men can occupy these positions for no reason other than gender. The Mormons get flak for having forbidden blacks to become leaders in churches, yet the Catholic church does exactly the same thing on the basis of gender. That's their choice, and I'd defend that. I just wouldn't be so dishonest as to claim that Christianity isn't practicing gender discrimination. The bloody thing begins with a woman leading a man astray, and that's a recurring theme. And that women, depending on which creation story you read, was created merely as company for the man.
Christianity says nothing (no matter what one church led by a guy called a Pope may wish) about controlling CONCEPTION. So we're not really arguing about not conceiving a child, but rather about killing a child that has already been conceived. Christians generally are opposed to abortion, not as a form of oppression of women, but rather because a baby is not part of a woman's body; it's another individual human being and Christianity generally frowns upon the murder of innocents. Christianity also explicitly forbids child sacrifice, unlike most other religions in human history. Killing a child for economic reasons, or social reasons, etc is no different from ancient pagans throwing their children into a pagan fire.
I'd agree that prohibitions on contraception are largely a Catholic thing, but aren't Catholics the single largest Christian denomination worldwide by a long margin?
Perhaps you see opposition to prostitution as "oppression". Well, it's generally not as "victimless" as portrayed; it creates a marketplace for the abuse of women, puts a price tag on all women, deprives any woman of the right to claim to be unemployed, and endangers women whose men cheat on them with prostitutes and bring home a few biological surprises. Women whose husbands give them a case of herpes or worse tend to feel a bit oppressed. For most of the past 2000 years, these things were considered advancements over the positions of nearly all other belief systems in human history where women were often presumed to be little more than bi-pedal farm animals.
Women had value because men wanted them and they could product offspring. Offspring in those times were both a retirement plan and your legacy. It's no wonder there were moves to protect women.
This is fundamentally different from the religion of Islam which explicitly values women as less than men, makes them property, denies them basic freedoms (including things like medical care in primitive locations like Afghanistan where it is practiced strictly and women are forbidden from being with a man other than a relative, and no women are allowed to be educated). Christianity also supports monogamy, which is a much better form of married life for most women than polygamy and spends more time teaching men to treat the women in their lives properly than it spends telling women to behave, so does that make it "oppressive" to men?
There's no denying that Islam is leaps and bounds more backwards than Christianity. But if Christian sects have advanced it is in fits and starts and comes by reasoning away scripture.
The Bible is quite clear. Women are made for men ( 1 Corinthians 11:8-9) and women should be subservient to their husbands and fathers.
Sure you can look at 1 Corinthians 14:34-35 and apologise it away, claiming that this was for a specific group of noisy women at the church in Corinth, but then how have people misunderstood this completely differently for so long?
And Peter 3:1?
"Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives;"
There's no arguing that Christianity is more modernised than Islam. I don't like either of the religions, but I'd sure as hell rather live in a modern Christian country than a modern Muslim country. And most modern Christians have adapted beliefs that kind of ignore the old teachings. Men and women to tend to have different roles and drives, which explains most of the gender pay gap, but the difference is that we do not forbid women from adopting traditionally male career paths. Most women could not beat me in an arm wrestle, but I know some can and I see no reason to exclude them from trying.
Your take on these different roles is close to the "separate but equal" doctrine than any modern understanding of equality. Christianity values men and women very differently, and I'm fine with that. Let them do what they want in their club, but don't lie and claim that it is not so.
