Global Trade may work out fine, if the laws were set aside from other laws, but what has happened is that by allowing Global Trade in practice (as seen in the EU)
is that you allow Global Migration, and Whilst Migration in it of itself isn't a bad thing, it is when you consider what I have to say in points 2 and 3.
I actually don't understand the point you're making here. Global trade and global migration do not have to occur simultaneously. We engage in extensive trade with China, but there is no special policy where,
because they're our trading partners, they get to send over X amount of immigrants per year. Trade and immigration are two completely separate things.
Milo isn't full Anti-Immigration, because some people do want to come to other countries with the intent of adapting to the civilization they are going to as well as
bringing their own culture to mix, but unfortunately with common Muslim culture, the idea is to force your ideas upon others. (no, not terrorists, but standard Average Muslims.)
The central dogma of our nation's origin is that we wanted a place where people could come and embrace their
own culture, language, and religion without persecution by tyrants. As far as I know, this hasn't changed, and it has never been an American policy to deny people the right to live here just because they do not want to sacrifice all of their ancestral culture.
It's funny that you cite Muslims as being some sort of invasive disease on culture, because the sole responsibility of Christians as servants of God is to spread the word about Jesus and convert as many people as possible (often forcefully, and against the will of native peoples) in order to spare them from damnation. However, despite the fact that we are a predominantly Christian nation, our laws haven't been written with the goal of converting people to Christianity. Why do you believe that Muslim immigrants are going to be able to completely rewrite our nation's laws, despite comprising an extremely small minority of our population?
Only Culture that forces its own culture upon others will destroy another culture.
Except this literally never happens in the context of legal immigration. Cultures mix and mingle when people live next to each other, but it's never some sort of oppressive force. Immigration isn't a slippery slope where you let a few Muslims into your town, and before you know it, all your kids are wearing Taqiyahs and fasting for Ramadan. The only reason miscegenation happens is because people consent to it, in which case, who loving cares?
