Agree. You are meant to think of ISIS.
It raises the "this type of violence is alien to our culture" bar as well because you don't just have to then prove extreme violence happens here as well already. But that specifically that type of violence does. And if you do bring in examples you can be accused of whataboutery or "so we don't need even more violent men then". Which is a bait and switch.
The Shankhill butchers for example carried out knife attacks just as horrific, but calling it a near beheading is supposed to make it sound like something a group like ISIS would do.
And I don't know if it was mentioned already but the same man who was unfortunately attacked had already been a victim of an incredibly savage attack when younger (tortured, drugged, doused in flammable liquid and set on fire if you want to know). The perpetrator of that attack wasn't just a white/Northern Irish man. He was a Loyalist drug dealer from Belfast. So the idea that the paramilitaries are now so shocked/upset at the level.of violence meted out to the victim is somewhat unlikely
I feel really sorry for the victim, and talking about the past crimes against him seems prurient. But it is relevant if people are going to be being up the "Alien to our culture" garbage.
