It's not a pivot, it's a natural conclusion to your logic. Republicans are automatically out, which leaves The Democratic Party, Third Party, or Not Voting as your other choices. Third Party isn't currently viable, and nobody took the last two years(or more) to create a viable third party movement, so that's out.

Which leaves now Not Voting or The Democrats. If Not Voting is your choice, you are already saying you don't believe in the system, or that the current Administration is alright by you. And if you don't find the current Administration tolerable, then that leaves you don't believe in the system.

Which is fine, but that leaves it in your hands to get organized and do something. Discouraging others to not use their allotted piece of violence doesn't help, and very much makes you look like an asset for The Republicans.

So again, if you don't believe The Democrats are the solution, then I must assume you're mad enough to fight The System. And if your choice isn't either one of those, then you're a Republican Asset, and should be treated like one.
