This isn’t a clever gotcha.
The hypothetical future majority that would be treating minorities badly would be a different group that the majority that’s supposed to be treating minorities badly now.
You’d want to look at how minorities are treated in the countries the immigrants are coming from to predict future behavior. The answer is usually going to be “quite a bit worse, actually.”
Ultimately, the immigrants are coming because they think the treatment of minorities in the new country is still better than being a majority in the old country. No one picks up and leaves because they believe it’s going to make their life shittier.
What do you think will happen when the files are released? That the World Police are going to take Trump away and lock him up in International Pedophile Prison?
No one is going to arrest Trump. He’s amassed too much power. Moaning about the Epstein files is a source of false hope, a distraction from all the new abuses that are occurring.
