Guys your pulling the same stuff lefties do when talking about terror attacks.
"if we deport the muslims/stop bringing them in it's only going to make them angrier/stronger and we don't want that :C".
No not really? That's not the same as beating up a bunch of neo-national socialists/white nationalists or doing something like tearing down a statue illegally because you disagree with the ideology of that person. In the case of people acting in a nonviolent matter like neo-national socialists and white nationalists protesting or stating their views in public, the best and most successful course of action is allowing them to speak, then debating them with better points.
That's not the same as the argument that deporting and curtailing muslim immigration feeds into radical Islam.
Beyond that, the argument you speak of is a form of capitulation, and I feel like we're not trying to bend the knee to neo-national socialists at all? I'm not thinking about the feelings of these idiots when I say we shouldn't be doing things that legitimize their cause. It's moreso trying to make sure both sides are held accountable for bullstuff at all times.
