How Can People Be So Ignorant?

Personally maybe I should not be starting a discussion like this, and I hope I do not end up hurting anyone's feelings, especially those who I consider Friends and I apologize if I do, but personally a situation has arose in that I find a little absurd and personally makes me wonder what this world is coming too. I am sure I will share a little more about things in some other discussions I might choose to start in the next 12 hrs. or so. Right now I am STRESSING and upset. There is some people at work who think I am racist. These are people who are Black and have always been against me from day 1. For anyone who does know, I as a white person am a minority, and people are always talking Bad about me. (It does not matter... I think they are jealous, and can keep their pidly ways, but that is not the point.) Personally I am far from Prejudice and some of my close friends are Black, so how can they really say this? It all stems from an issue I was talking about regarding Obama's Health Care and I was saying I can't see how it would help and I feel Sorry for those with chronic problems like I have as it will be even harder to get Good help then. And she thought I meant because Obama is Black. I then said he is mixed as his Mom is white, and she said no he is Black and I am racist. If I am wrong pinch me, but how can you not be mixed if his Mom is blonde and blue eyed? Seriously she told my husband about it, and said she was going to say something to my Boss even and try to get me in trouble. What she failed to mention is it is also all over on Facebook and such, and I copied and pasted it in an Email with their names, etc. and going to be making some calls in the morning to my Boss etc. about this. Personally I think this is going too far... And since their are threats on their too... Wow!! But hey personally if this is such an issue I guess I was wrong, but personally I thought this was a Free country for people to share their opinions. Or am I wrong? ~~TINA~~
