i think it's important to realize that this is happening because the system - both in the united states and here in canada - requires some reform. you can't scapegoat migrant workers without the existence of economic uncertainty, and the cultural issues exposing themselves are entirely real. i'm currently fighting with neighbours that moved into my duplex and expect me to abide by islamic law because there are muslims in the house. that's not how we do things here, and isn't how we're going to start doing them, and i'm not about to start abiding by islamic law, but it will be if they get their way and people don't realize that the legal system of democratically enacted laws and common law (judge made law that can change, and is not fixed to the dark ages because god says so) needs to be supported and won't continue to exist if it isn't. if you don't support your culture, it won't exist anymore.
trump is kind of right in a sense; you need boundaries, or you don't have a country, don't have a culture and don't have a society. the question is how to do it fairly and reasonably. you don't need to mirror the islamic extremists to protect your culture; indeed, it's better if you don't.
activists should insist that anything and everything coming from trump and the republicans utilizes due process. there are people that won't be able to stay. they need a fair process.
however, there are also currently very real economic and cultural concerns at play that the left needs to adjust and react to, rather than kneejerk or dig in on. i want a secular left to support, so i don't have to juggle the fact that i'm not in the same class as the right-wing political base and there are economic ramifications of that with the reality that that very truth demonstrates economic value in specific right-wing xenophobic positions. i don't want to be forced to balance that. i want a more realist left, like currently exists in quebec.
