I have not seen many leftists not agree that both votes are for genocide - that's just a given.
But protesting the system during the election is daft. Do you want genocide, or more genocide? You are not a slave to the system if you vote and then actually do something about it to change it.
Ignoring the current system is plain ignorance. Voting doesn't make you a slave. Voting and giving up makes you a slave. How about vote and campaign for change instead. Despair does not lead to change.
But if it was a 20 year old man with a 15 year old girl, would you still not mind?
