That's his opinion. Tens of millions of other Americans don't think so at all, and they're making their voices heard in national elections and successfully choosing our leaders.
Suppose that every year the federal government gave each family a baked goose to celebrate our acquisition of colonies via the Spanish-American War. You can think this is an offensive celebration or a crazy waste of money, but why not accept the goose when it is delivered? It's still a tasty meal, even if you think it shouldn't be given out.
That is what is going on. It's not hypocrisy, hate, or inconsistent principles.
