You have to consider that Vietnamese moving to Poland are pretty smart: its no secret that Poland is relatively right wing and racist, so if you wanna emigrate there you quietly move in, quietly get a job, and quietly get on with life. You dont start shit or the backlash will be brutal. Germans need to get their shit together. England, Sweden, many other places also: These kids wont listen in school so they dont have an accurate picture of how Europeans are historically: we want to do our thing and not be fucked with. You throw your weight, we move a bit, but push too far and we fuck your shit up. No part of the world has surpassed the West.
We nuked Japan. We, the west, dropped 2 nuclear weapons on an enemy state. Noone else has done that. The house of Othman ran rampant over the Byzantine empire and the west barely did shit. But then they fucked up when they came into mainland Europe and thought it would be the same. It wasn't. We mounted the largest cavalry charge in all of recorded history and fucked them up.
I'm scared that these fucking scumbags will keep making our society worse, and we are gonna react the way we always do. With ultra violence. Historically we haven't been bested. Even Spain: under the Caliphates, Al-Andalus was a great place to live, but we couldn't let them keep it and even if it took 600 years we fucked them up and took it back.
I'm not defending violence, or promoting it, but we have to look at the history of the West: when we are pushed too far we are even polite enough to say: HERE is the line. You are warned, push once more and we WILL stop you. We fucking do it to each other also. Look at WWI: England was tired of Imperialist Germany. They didn't want Germany having Belgium: 1/ they were our allies and we had sworn to protect them. 2/ Germany having Belgium ports was a real threat to England. So England said: if you fuck with Belgium we WILL fuck you up. And Germany LOL'ed and marched thru Belgium into France. Less than a day passed before England declared war on Germany. In Europe we have a limit.
Im so sad that we have worked so hard in Europe. Say what you like about the EU but we have had the longest peace in Europe since EVER. We welcome others into our countries with open arms, give them houses and free education, and they cant even control their kids. Slowly we creep to the right wing again, because its the natural way to feel. Next thing you know these same immigrants who were happy to throw shit at reporters, act like they have their own rules and shit, will be the same ones crying for news cameras to come and see how they are being incarcerated in camps and treated like shit. But noone will come then, because why would you try to help people that have violently rejected you?
TL:DR
If they dont stop fucking around, it will be on them, historically we have fucked over everyone who wont cooperate and the reality of how well we defend ourselves in Europe will not be pleasant or pretty.
