It isn’t a case of them being thumbed to the top, it’s YouTube promoting them because they have caused a discussion and YouTube likes discussions (this is an algorithmic failing that I am not fan of.)
You can only thumb up a YouTube comment, not thumb it down. We all know that there are bigots in the world, so it shouldn’t be a surprise that some of them leave comments about how homosexuality is a disease or whatever bullshit they’re spewing these days. And it also shouldn’t be a surprise that a few people come along and agree. Those people exist, we shouldn’t pretend they don’t exist.
Of course, by promoting the comments that cause discussions, and not allowing people to vote comments down, they’re giving undue air-time to controversy rather than validity. If you look, the first reply to every one of those comments is a rebuttal, and each one of those has five or ten times more upvotes than the original comment.
I don’t think a follow-up is necessary, I think we said exactly what we intended to say in that episode, and it’s being received well by the vast majority of people. The rest of them well…it’s more about their identity and their worldview than it is about reality, and that’s not the kind of discussion we have at CrashCourse.
