You posted these two sentiments in two consecutive posts. In the first, you are saying that you aren't interested in "listening" (even with the smiley). In the second, you complain about people that won't listen to you. Shouldn't the listening go both ways?
I don't think that it's hatred so much as each side being so sure that they are correct that they immediately discount the ideas of the other side. Bush used to be so sure that he was correct, that when people didn't agree, he would repeat it assuming that they didn't understand. They understood, just didn't agree. Both sides have this problem big time.
