Over My Head

Why is it when I think I get something, it is apparantly way over my head? I can be sure I get it, then everyone else disagrees with me. Case in point, on FB my friend Cecil wrote a note about eco-liberals. While I didn't agree with all he said, I felt similar to a lot of what he wrote. He was very angry when he wrote it and that definately came through, but it was a good article. So far I am the only one who thought so. Now I am second guessing myself and wondering if I sounded like an idiot in my comment. Argh! I dislike that strongly about myself. It is just like when I put the Obama book I was reading as my status. My uber liberal cousins haven't spoken to me since. I wonder if I am offensive and/or uneducated sounding. I wish I didn't always have to wonder. I should feel confident enough in myself and my opinions.
I would never dislike anyone or drop them as a friend because of their views. My sister loves Obama, I still love my sister. I even like the girl! I don't dislike people because they are gay, a different race, etc. I see what's on the inside and I like a person for that. Not for what they look like.
