The more people that stand up to things like that the better. We shouldn't just accept things getting worse. It's hard to do much about, but I've enjoyed the TV show here where a couple of people have searched out severe trolls on the web and confronted them in real life about what they've said. Quite fun to see them shrivel away when confronted in a non hostile manner.
Saying that it's just how it is, and then criticize Chris for being "********" about the memes he said he actually found funny is not something I personally find very productive. I don't see why he would have a huge problem with such given that a Youtuber with such a big following is sure to get lots of normal hate regularly.
