The fact is, the tea baggers have revealed their racist tendencies over and over again in their political demonstrations on the streets. They have done it to a degree that denial is just not possible anymore.
Obama is a black president that is seen as attempting to elevate the miserable lot of blacks in your country. That's not his only purpose but it's being seen by his detractors as being so. And so, even though I don't expect honesty from you, that's no reason why I shouldn't be totally honest about what it's about.
When Obama is gone, things will change abruptly. The lot of the black people of America will most likely be put on the back burner for a time at least and there will be a moderate degree of political peace.
The reason I know this will happen is because the bagger agenda is based on intangibles that are impossible to be the agenda items of the ordinary American. It's only because of racist hate that the Koch brothers and their ilk have been able to capture the undying support of the little guy.
I've seen it happen in a somewhat similar way in my own country with the REform party. It became a marriage made in hell of extremists from both the left and the right. It died because they didn't have anything in common other than an irrational hate based on them being coopted into believing in the agenda of the wealthy. The tea bagger agenda will likewise die too when the hate fades away back into the closets of the southerners.
