Especially considering there people consider themselves to be the “tolerant” one’s

Where does this come from? Because the only people I've ever heard use the term "tolerant left" were people on the right.

This is all just decorum tone-policing, a way conservatives and those in the status quo quiet dissent by holding oppositional voices to a higher standard than they hold themselves. As a leftist, I believe in equity, I believe in free expression, and I believe in not judging others by their intrinsic and immutable qualities such as skin tone, familial background, and appearance. But I also absolutely believe in judging people on the defining characteristics they choose for themselves: their words, their actions, and their beliefs. I'm left as fuck, but I'm not going to tolerate hate, or exploitation, or evilness; don't call me fucking tolerant.

To that note, you'll notice religion (in terms of belief, not background; there are some cases where this muddy) falls squarely in the "what I believe" section, meaning that is the kind of thing we should judge a person's character based on. And tbh, since Christianity, especially Western popular evangelical Christianity isn't exactly a neutral or non-impactful influence on the world, why should it be spared legitimate criticism? If we leftists believe in building a better world by repairing or tearing down and replacing broken systems for the sake of the betterment of mankind, why is that particular system (which again, is not neutral on non-impactful in influence) supposedly off-limits? Why are you okay with us raging against all of the other machines oppression but that one? Why are you okay with the righteous work of changing minds and educating others against governmental structures but not religious ones?

Somewhere down the line conservatives tricked leftists into thinking that "don't judge people for their skin and background" should stretch to "don't judge people for the literally insane shit that they believe despite the fact that the insane belief will literally inform all of their choices, both legislatively and personally," and it is absolutely fucked that so many leftists have fallen for it.

Don't judge people for what they are; do judge people for what they do, what they say, and what they think.
