@Lash,
Not his racism nor his Greek heritage.
Your analogy doesn't work, nationality is not the same as political/religious beliefs. Unless you move to a different country and become a citizen you can't change it, and even then first generation immigrants still see themselves as having their original nationality if not their rights as citizens.
People don't prefix every response they make to you with a sentence disputing your political beliefs.
You talk as if you're being picked on, as if such comments were without foundation but they're not.
Firstly you admitted voting for Bush twice, that's quite a right wing position to start from, especially as the second time he'd already allowed 9/11 to happen then started an illegal war. I'm not saying people don't change politics, they do, but normally in their teens/early 20s not in middle age.
Let's give you the benefit of the doubt, which I have been doing, and say your conversion is genuine, that doesn't explain your current behaviour. You're very friendly and chatty with Layman, a blackface racist who posts transphobic bigotry, someone I find beyond the pale, yet you're extremely confrontational towards Revelette someone with whom I have some ideological differences but whose heart is definitely in the right place.
Like the saying goes if it looks like a duck.. You may occasionally say quack but you don't look walk or talk like one.
I would love to believe what you say about your conversion to progressive politics but I can't see anything substantial that proves it. What I have seen is an attack on most left of centre posters, a cosying up to the right wing ones and a determination to split the Democrat party.
When the gang of four left the Labour Party to form the SDP it gave us five terms of Tory Government, and splitting the anti Republican vote will keep them in power until the 2030s at least.
From here it looks as if that is what you want.
