If Trump influences you, you already had weak values to begin with. Some people's morals are made of sticks and feathers, people like Trump puff on them and the charade falls apart.
When Trump's gone there's going to be more like him, obviously. He proved you can have a successful political career being a piece of shit. Even if you do take the bigots to task, so what? What changes? If trump is impeached there's still millions of bigot voters out there that could vote for the next Trump. Even if a democrat succeeds him afterwards... there's still millions of racist voters out there that could vote for the next Trump in 4 years, in 8 years, in 12 years, in 16 years, and so on. We're always going to have the anxiety of that risk because we have a large section of the population that are literally cultural filth.
