It is beyond me to understand why your post was "hidden." We don't even have a Democratic presidential candidate yet. So that isn't the issue. And that you state that you won't vote for just anybody because they have a "D" after their name is a perfectly reasonable thing to say, whether we already had a candidate or not. This is the Democratic UNDERGROUND. It is not the DNC, a state party organization or any official organization at all, connected to the Democratic Party. "Underground" to me means healthy open discussion of all matters and high tolerance for alternative views.
We have had this "underground" ethic in the past. We still post alternative views and pro-Sanders views without admin interference. But Clinton supporters do NOT share this "underground" ethic. They operate here strictly as propagandists, and often disrupt discussions (with nothing to say, or with empty snark) and swarm after Sanders supporters, using the "alert" system and the jury system much too often, and with very ill effect. I would guess that they have antagonized every Sanders supporter on this site.
I'm sorry that you've been their victim. I honor your views. You are absolutely right--no one "owns" your vote. No one "owns" mine either (lifelong, 50+ year Democratic voter and activist).
