I don't. It's easy to be cynical, but the internet in particular has given birth to or allowed to flourish a number of...interesting communities. Not to mention tolerance on a number of dimensions, like race, gender, and sexuality, is way up. You could argue that it's not that we're nicer to "weirdos", but rather we've expanded the bounds of what's considered non-weird behavior, but at that point you've basically just used circular reasoning: "Niceness to weirdos is constant because I define weirdness such that niceness to weirdos is constant."
