It is! One of my best friends who became very vocal against drag queens reading to children and trans kids' rights has fallen into a deep rabbit hole of alt-right radical conspiracy bs on YouTube. He also started sharing toxic masculinity guru videos in our group chats and videos from Ben Shapiro and Jordan Peterson for example.
I tried to give him counter arguments with examples and other videos, but when searching for content on YouTube, I had difficulty finding anything because, most of the content when searching for certain keywords, was just videos of alt-right talking heads.
Social media companies like Facebook, Google, Twitter are pushing an alt-right conservative agenda and their conspiracies. It's pretty appalling.
