In the UK, where I live, some schools started to host seminars for parents on the topic of incel ideology, and online radicalisation in general, to at least make sure they know what their kids could get into while being online. I've also talked with a few school counsellors here who are putting together de-radicalisation programs for their most troubled students.

It might not seem like a lot, but it's good to know something is being done about it.
