That is honestly a fair concern. I think a lot of the more dangerous extremism is born of segregated or heavily polarized communities online that is radocalizing people. As someone on the left, I definitely see that way more clearly with extremists on the right, but it would be arrogant and smug of me to suggest the left isn't likewise influenced. I don't know how to fix, though. When people are free to go to where they please to participate in conversations and avoid places they don't feel welcome or may even be hostile toward them, it is not shocking so many places lean into one ideology or another.
