My thinking is that we all have biases -- it's how our brains are wired for survival. Whether you control them or you let them control you determines whether you are racist/sexist/tropist. I think we should allow some leeway for people having biases; don't shun them just because of some questionable statement, but do let them know if you find it objectionable. Where racism hurts and often should not be tolerated is when it has an impact on a person's major life choices and economic opportunities. I think that is where the government often needs to step in. Life, liberty, and the pursuit of happiness, and all that whatnot. Thanks.
