I might get slammed for this but immediately after 9/11 the world changed for many people.
I was young at the time, and it is formative years. Before that time, I was not as much in to politics.
So, it was a different time for me. After 9/11 I felt that we should support the leadership for the nonce, till we find stability and bounce back. Unfortunately, I found myself bamboozled. He used that goodwill to promote a crazy war agenda, cut taxes, increase privatization and many other atrocities.
A year later, they heavily pressed on the media to sell the war in Iraq. Sure, there were reservations, but given the flawed intelligence and the usage of Colin Powell, the Iraq War went through. This, much to the dismay of many, the reasons were false. As for me, I didn't want it, and thought it was ill advised, but I didn't feel too strongly about it if it were to happen. In that, it was a tepid acquiescence. Not actual support, but I thought it understandable at the time. I was wrong, especially when more information came out.
Needless to say, I felt betrayed. By 2003, most of these were already well known. I supported Kerry enthusiastically, and went from the Kerry boards to cgcs, which was hosted by some of the admins from there.
I can never support the Citizens United Decision however, as that is some crazy idiotic sh..
So yeah, I don't think absolutist measures in regards to what is "Left" and "Right" really helps. It just divides us, and I think 2014 is very important.
