Obviously , because its a 'slippery slope' you feel its ok (not ok in the sense that you support it but more that they have the right to do it)for those people to recruit kids to become killers, propagande terrorism,rape , murder etc....
then what do you propose? we let them go....see where it leads? see what happens?
How about the social media platforms police their own sites and actually moderate against Terror?
Instead of this thoughtcrime, surveillance of the public bullshit.
