It's not deradicalised people who were already on the left. It's just that people making these vids are just radlibs, and they don't know enough about anything. Almost none of them belong to any kind of larger structure, to an organisation or something, or have participated in serious organising and unionising etc. A leftist who has never tried any of that stuff, has never come in contact with serious people who are attempting that, who has never been part of collective struggle etc and thinks they are qualified to talk about stuff after just reading the wiki page about Rojava or even worse, watching vids by other libs who stan democrat slay kweens, is not a leftist.

They're all either utopians, laser-focused on idpol, secretly reactionary or just complete ultras. And that is predictable. It is also predictable that if they continue being as individualistic as they are, if they continue being absent from any serious organising, and if they continue having their audience enforce their echo chamber, chances are they will all end up reactionary.
