You ask for criteria on when it's too important to vote 3rd party. I give you criteria. You say, it doesn't matter, I'm still voting 3rd party. What was the point of that whole interaction if nothing could possibly change your mind?
I dunno about you specifically but one of your ilk convinced me that Social Democracy is not really socialism and is more like a flavor of Liberalism. Just off the top of my head. Another one convinced me that some forms of anarchy are a viable system of government, though not my preferred one.
I don't understand. My ilk? Care to clarify what ilk I am of?
And because people you knew talked about social democracy and anarchy, you decided that I must have some sinister agenda?! I'm not clear about the connection you are making.
