I mean how far are we expected non-Muslims to tolerate this type of nonsense before they start attacking anyone who even "looks Muslim"?
They will not do that. If the feminist State allows the men to assert themselves, then these men will soon seek to rule over the women again. That would put an end to the feminist State. Hence, the feminist State will not allow it. At the same time, the feminist State is wary of recruiting too many men, tasked to assert themselves, because that would invariably lead to the same problem. Therefore, getting non-Muslim men to attack Muslim men would trigger an insurmountable contradiction within the feminist State. They will only do that, if it is very easy to do. Otherwise, they won't. So, if you make it even a little bit difficult to do, they will already not do it.
I suspect that the only way for anybody to trigger this kind of confrontation, would be to talk the Muslims into doing that. That would be quite hard too, because most Muslims are aware of the difference in birth rate and the fact that time and demographics play to the advantage of the Muslims. The longer the Muslims delay such confrontation, the more likely they would win, when such confrontation eventually takes place anyway. That explains why there is a strong undercurrent in the Muslim community that understandably does not want this. Seriously, there are a lot of Muslims who will be angry with you, if you try to talk them into things like that. They may even repudiate you.
The phenomenon of extreme individuals in the Muslim community, attacking pagan populations, mostly exists to keep Muslims and pagans separate, and to prevent both sides from making too much friends with each other. It keeps Muslims distinct and segregated in order to prevent them from adopting pagan views. The few extreme individuals occasionally popping up, are in fact an intractable problem that purposely arises in order to keep festering and to prevent itself from being solved. The more that Muslims are perceived to be making friends with pagans, the more that the problem will fester, and if the problem accidentally did get solved, it would later on just re-emerge in a different form or shape.
