How is this not childish, though?
I know a decent amount of Latino millenials who did exactly this - supported Bernie, weren't feeling Hillary, and thus stayed at home in November. Now, these same kids have family members, in some case parents, who are pressed because of the result. These same people are now protesting in the streets when all they had to do was hold their nose and vote.
It's completely selfish and comes from a place of privilege and / or ignorance to me. If you vote for your candidate and they lose in a primary, OK. Now nut up and choose or have someone choose for you. How does opting out in a general in any way rectify the situation? It's passive to the point of being putrid.
To make it worse, the very things a lot of these voters desire become less and less achievable the more power they cede to the other side through not voting. The gears of the system turn with or without your participation and you can either turn them or have them grind you.
I see your point of view but in response to what i was saying, this still does not alleviate the issue which is casting a defensive vote is not actually casting "your" vote.
The two party system perpetrates this and there is really no resolution until another group pops up...which we know is not happening any time soon
