What does it even mean for a "group" to "attack" another "group"? What constitutes an attack? How does someone have to be related to the attacker or victim to be considered part of the group?

Are all Muslims guilty of attacking all Americans? Are all Americans guilty of attacking all Afghans? Does a "gamer" saying mean things about a girl on the internet justify intollerance against anyone who plays games?

Is it all just framing used to justify hating people for bad-think?

I'd be lying if I said I didn't get it. Democracy is interesting. It enables sufficiently large groups to turn their thoughts into actions through the works of a few representatives. That's a good argument for bad-think being dangerous. But on the other hand, refusing to tollerate someone for bad-think surely leads to resentment and division until one side inevitably gains the upper hand and uses it to crush the other.
