Perhaps one day you will evolve to love males.
This is stupid. There's lots of kinds of love, and there's plenty of reasons why BarbaraHudson would likely not be sexually interested in me. Since I never intended to have sex with her, I don't see why I should care about her sexual orientation.
Religious people are delusional.
People who say that are delusional, in that they think they know that religion is bunk, but in fact there's no evidence either way. Absence of evidence is not decisive evidence of absence. (It's easy to prove that a majority of people have false religious beliefs by consulting a reference work. Christians, Muslims, and none of the above are all minorities, and they all disagree with one another.)
Torture works. Historically proven.
True, but not for everything. Torture is very useful when it comes to coercion. You can get somebody to confess to anything they did, or anything they didn't for that matter. It's not good at finding the truth. It is, however, very useful if you want to band people together for immoral purposes: have each of them torture somebody.
Healthcare is not and cannot be a right because the demand for it is infinite.
That's stupid. First, the demand for healthcare is finite. Since there are a finite number of people, for demand to be infinite it would be possible to spend any number of resources on one person's health care, and I don't see that happening. The potential demand is larger than we can reasonably supply, but that doesn't mean there can't be a right to a reasonable level of medical care.
There continue to be many factual opinions that cannot be freely held and expressed without being persecuted. Thus the need for privacy and anonymity, even if it is only partial.
In certain places, yes. In general, I can't think of any. There are people publicly in favor of legalizing all drugs or having sex with young children. I've publicly asked for research into child pornography to find its actual effects. There are people out there who defend terrorism and terrorists. As long as they don't do anything, they appear to be mostly ignored. As a test, specify an opinion on facts that you think would automatically be persecuted. Then look for it on blogs and Slashdot archives. When you find that, check to see whether and why persecution occurred.
There are situations where it's safer to not express certain opinions, not everywhere. There are societies where I'd just let people think I was Christian rather than correct them, for example.
