Btw, I donno how's the situation in your guys' countries but in France it's very understandable that nationalism is rising. A lot of corrupted people exploit immigration to make money for themselves and manipulate foreigners for political and business reasons. Also there is a lot of intra-communities who work for other interests than french interests. For example, we've got a lot of politicians who openly said they would do anything to help Israel, a lot of them wore a kippa at some point in their life. There is a lot of censorships on subjects as immigration, jews and Israel. A lot of jobs are completly dominated by jews as journalism for example. There is an unfair treatment between people from immigration, random people or for people who openly support Israel. You cannot make any jokes about jews if you are not jew yourself or well-known supporter of Israel. There is some very well-known sionist terrorist associations in France that acted openly against other french people who disagreed with them. By acting I mean assault with weapons, kidnapping, blackmailling, public humiliations, etc. Everyone and their mothers know this and yet it is completly ignored by people in power. A lot of stuff like that to be honest.
I'm not trying to throw any hate in this, I'm just stating what I see from my point of view and the information that I've got, which is obviously more or less biased and partial. I've never been in any nationalist demonstration and I even never voted for the nationalist party in France. And yeh, I'm not a jew hunter either, it just feels like they are traitors when some of them work in France for Israel, if you see what I mean.
