Voting for Biden isn’t approving genocide at all. Unlike you, a person can have multiple characteristics you can be in favour/against. Because humans are complex.

And anyone can see that every viable alternative is worse for Palestine. Since not voting or voting third party will just increase the chances for Trump to “finish the job”.

So if you actually cared about Palestine to survive, your best bet is to vote for Biden.

But it is quite obvious you don’t care about Palestine. You just want Trump to win.
