You can look him up if you are interested, he's on youtube and also widely discussed.
The reason I bring him up is because my brother and cousin see him as a man bringing forward the gospel of what's really happening in Europe. Islam and Muslims are the new evil (like the Jews were before and during WW2), and he use what he portrays as facts to support his views. He also use a very depicting language to play directly with people's emotion. Well dressed, well behaved with eloquent language skills, he portray a responsible, middle-aged white man with genuine concern for the future of Europe in particular and the world in general.
Another observation is that his disciples argue very much the same way as we do here regarding Trump - and that goes for both his supporters as well as us who see him as more or less a horror; both sides are equally convinced about their own correctness and cannot understand that anybody can be so stupid as to not grasp the obvious reality. The reality is somewhere in between the opposites, naturally.
Anyway, IMO Islam or Muslims are NOT the problem. Individuals who use the religion to control the population - usually illiterates - and create terrorists are. Going after groups and stigmatizing them instead of judging individuals is racism, nothing else. And there is nothing to suggest that Islamist will constitute even 10 % of the European population within the time span we can foresee, so the group will remain marginal. And the risk of being killed in a terrorist attack in Europe is next to zero. That doesn't mean we should not take terror in earnest, but that we also need to be realistic about it all.
This is worth reading IMO
