Probably the same reservations I have for any political party. A political party is not there to represent me. I can do that well enough on my own with my vote. I only need political parties to provide candidates and put pressure on other political parties.

That's still not specific. You said you want to tut-tutt the Democratic party for not being centrist enough and for holding extreme positions. Which ones?

I never mentioned any party. I refuse to vote along party lines.

And I never demanded you do. I did ask, however, what the "extreme perspectives" you meant upthread were in the context of democrats. And I note you still haven't answered.

At least one reason might be because democrats aren't actually as extreme as you feel like you're Supposed To Think. You might consider voting for some if you look at their positions instead of jumping in to complain about their "extreme perspectives".
