That's a reasonable take, for sure, and it makes a lot of sense.

However, it is a bit of a rationalization to explain to yourself why you support her. It is analogous to not voting because you don't think you'll sway the election, that your vote doesn't matter, in the sense that if enough people do it it does begin to have an impact.

Also, it isn't about not giving her a lavish lifestyle, it is more about sending a message that her brand of hate isn't welcome or tolerated. While she will make millions off of investments, if she sees that her bottom line was hurt because of her words she may, ideally, re-think them. Perhaps reflect on them, in a perfect world.

Admittedly, in reality she probably will only dig in deeper and feel victimized. But at least I'll sleep better at night
