I agree with your sentiment; live and let live I say, really. I don't want to discriminate.
But I still have to disagree about religion. There are countless perfectly legal things people can do that I would consider a mistake. I consider it "not wrong" to consider these things if I need to evaluate someone for any reason.
That religion is legal, common and influential does not change that one bit. That its followers might be brainwashed doesn't either. That's hardly a pass.
We all judge people, there's no high ground here. But we're drawing lines and I'm saying there's what you're born with and there's your actions. Gay and black are the former, religion is the latter, as is every moronic thing you've ever thought someone was an idiot for doing.
I'm not making a call here saying religion is one of those. I'm just saying it's not wrong to judge them both the same way because they are both ultimately decisions.
Regardless even of what action is taken the decision itself can be judged without shame because it's on you. No one else can make it.
They can try. But you're always your own last word.
To suggest otherwise is to say that people are born into or beholden to religion on the same kind physical level as, say, being born gay. No way. Being Christian is not the same as being gay or black. Being Muslim is not the same as being trans.
It's a lifestyle, a choice. As such, fair game. Own it or fix it.
Judge not lest ye be judged, indeed.
