I notice you left out “Persuasion.” If you think the presentation of facts regarding the basic function of our voting system is somehow force, coercion, or manipulation, then I can see why you would want to do your part to get Trump elected, and you’re a lost cause.
Either Trump or Harris are going to win the election. No third party candidate has any serious chance of winning, and nobody who actually understands how the election works thinks they do. You are ALLOWED to vote third party if you want to (see how nobody is FORCING you not to?) but doing so is just another vote the real contenders don’t have to beat. If you’re more left leaning, that means it’s a vote Harris would have had that Trump doesn’t have to beat.
I haven’t called anyone a Russian Shill, sounds like a guilty conscience. And again, nobody is forcing you to vote in any particular way, you absolutely CAN vote however you want, for whatever reason you want, but there are consequences. You could vote for Jill Stein, you could vote for your neighbor’s cat. Both have the same chances of winning the election, and both are another vote Trump doesn’t have to worry about overcoming in his effort to win. No matter how hard third parties try, none of them will ever, ever get more votes in a presidential election than the big two, and the more people you sway to your side, the fewer votes the main candidate you otherwise most agree with will get. Welcome to First Past the Post voting, nobody likes it but it’s the system we have. If you want third party candidates to stand a shred of a chance, you have to change the system of voting, which would be ideal.
To be clear, I completely understand WHY someone would want to vote third party. The thing is, that literally doesn’t matter. Only the result matters. Like you said, people can vote how they want for whatever reason they want, but they still only get one vote. Either your vote will contribute to Trump not winning, or it won’t. Nobody said your third party vote is a vote for Republicans, but it’s not making their barrier to victory any more difficult, they’re already guaranteed to beat any third party opponent as it is.
If you don’t care about that, and you just really really want to stage your protest and hope that Mr. Worst Case Scenario still loses, that’s on you.
