If you insist they give up their culture immediately you will be seen as trying to take away their culture. Just like how gun rights advocates perceive attacks on gun culture.
Solidarity is a normal reaction to real or perceived hostility. In history the social pressure to assimilate resulted in immigrant collectivism in order to support each other; Chinatowns, little Italy and a myriad other ethnic enclaves formed partly because of this pressure.
Well I mean, this post started as a much more broad conversation about immigration. You even provided links to Germany and UK immigration policies.
Your just playing ignorant if you don't know what I'm referring to with the immigration crisis in Germany, Sweden, and France. They have countless terror attacks. There are no-go zones. There are riots. Its chaos. It is no longer safe. Rapes are up. Assaults are up.
So you can use that as a guide for what will happen to North America if they continue to adopt the same policies as Germany, Sweden, and France.
The Muslim faith tells them not to assimilate. I have no problem with any religion, as long as it is not trying to have an impact on my life. But there are leaders of mosques in Toronto openly calling for the destruction of Canada. Openly calling for Sharia Law. On video. If they don't want to assimilate, they should not be coming here. It makes no sense. There are Countries that have Sharia Law. I don't understand why they think it needs to be brought here. They have the option to just stay in the country that currently runs under Sharia Law.
