Ol’ VDH, bless his heart, tries to explain:
Why today’s immigrants to America are so hostile to their new country
Now you can go off and read what he says in 10,000 words, or you can accept my simpler explanation.
These motherfuckers are so hostile towards their new country because we allow them to be.
You can dress this up, posit all sorts of reasons and rationales, but there’s a simple truth: yesterday’s immigrants (e.g. me) came here to improve their lives; today’s immigrants came here to fleece our goodwill (Somalians) or actively try to destroy our country (the pro-Palestinians et al.), and they are able to do this because we let them, instead of kicking their asses straight out of the country using high-speed transportation systems.
It really is that simple.
