They're just thoughts, even broke people can afford those.

I'd say that's an ethos rather than an ideology.

Sorry but I really don't think it's the same thing. People are motivated to do this to oppose an ideology, not to promote one. They could come from almost any ideological starting point, and all they want, essentially is a return to the status quo.

Again, which ideology does this action promote?

This is resisting, not furthering, ideological goals.

Could you state the ideological goal of these attacks?
