The only virtue of a wasted vote is the personal satisfaction that you get out of it, and that personal satisfaction has no real world effect on politics unless you are voting for a visionary with overwhelmingly popular support. (i.e. you would know if one is in the race)
if i’m wasting my vote then i may as well not vote at all. but i’m going to vote and it’s going to be for someone who won’t sign off on genocide.
