I dislike the racism and white supremacy; I downvoat those comments and feel good when they become hidden. But I am also glad to see them. Not because I agree with them; I do not. But because seeing them here reminds me that this is one of the few places on the internet anymore where you are not censored and banned for saying men can't be women, or fat people are gross, or Trump isn't the devil.  More than that, seeing that the (very) rare racist comment that is genuinely funny and clever is still visible/doesn't have too many downvoats reminds me that not only is this a place where free speech is allowed, but it's a place full of people who use their brains and read what the commenter is actually saying, and are open-minded and humorous (and generally good-natured) enough to appreciate a good joke even if the subject is taboo, instead of immediately screeching that, "X is never funny! You shouldn't joke about that!" It reminds me that this is a place where one "wrong" comment or opinion is not going to brand you as an evil person, even temporarily. In a weird sort of way, seeing opinions that disgust me openly displayed like that remind me that most people are reasonable and decent, and that this is a good place. So that's how I try to think of it, if it helps. I see it as a necessary price to pay for free speech, as proof that this is a good place with good people, and, actually, as proof that there really isn't a need for censorship, because the community can condemn such views easily without it.
