No, I don't think that the sign is racist. It would be racist if it said that the white race is superior though.
As the report says the sign was posted by KKK. You may not find KKK racist. But the vast number of people in the U.S. will disagree with you.
The question was is the SIGN racist.
Your admiration of KKK is not against the law. You are entitled to that.
You're nothing but a rotten troll. Go back under your bridge and don't let me see or hear from you again.
This is what happens to people who take a position which is wrong and cannot be defended. If you take a wrong position on a public forum, you will be called on it. It is that simple.
