Can you elaborate on this? To me, again just being honest and genuine, it reads as a racist dog whistle which says “without a shared cultural baseline this country will collapse”.
I’ve worked with local immigrant advocate groups and have multiple immigrants living on the same street as me. They largely want nothing more than to be part of American society. Is this a range? Absolutely. Different people want to be part of society to different extents. But it’s very rare to find people who won’t be kind and welcoming to you if you are kind and welcoming to them.
On housing that’s obviously true. There are two solutions there. Reduce the demand, or increase the supply. Given that the demand is “humans wanting shelter” any attempt to reduce demand is clearly immoral. So the answer there is to up the supply.
I also genuinely want immigrants. At a minimum they bring delicious food I get to enjoy.
