Why do you think it's "misery" to not live in perpetual fear of people that might be a little bit different from you? People that, for the vast, vast, vast majority are coming here for better conditions, often times because the U.S. contributed to the **** conditions in their country? 

And if you're arguing "replacement theory" which you're really close to, which Kirk and Carlson both explicitly argued, then you are, indeed, a racist. Societies aren't concrete, inviolable things. Nearly every immigrant group has been discriminated against because - well - racists, frankly. If you don't like being called out for advancing clearly racist ideology - then, don't. It's pretty simple.
