You seem a little daft. So I'll help explain in easier language.
Trump, bad.
Biden, bad.
If Biden win, u get 4 years to protest and complain about policy until your voice is maybe heard, and either way then see new candidate options.
If Trump win, u no get chance for new candidate after 4 years, cuz he's a fucking psychopath and won't give up power. And solidification of more and more power will entail recruitment of more and more zealots which is a path he has shown he is willing to take.
It will show other power hungry nutjobs coming up that the Trump method works and to get even more radical in future campaigns/movements.
Then the future zealot-Maga-NeoNazi mob will take complete control as they'll be planted in all key aspects of government and military and police (already there most likely) and they will normalize hate and start rounding up all the types of humans they fear/dislike or that don't agree with their views, and they'll commit fucking genocide on your home fucking soil.
So if you vote for Biden, there is genocide but you're not complicit simply because you pay taxes.
And if you don't vote Biden, there is even more genocide, but possibly to people you know and love, and you are complicit because you failed to act, and you can kindly fuck off with that dumbshittery.
