Here's the biggest problem with these type of threads, what do you want random internet strangers to do about it? Ok some idiots are potentially racist. What is the point of the thread? Just everyone sitting in a circle going "Hey those people are bad"? All you can do is make it known those people are potentially bad people and move on. What else would you have happen?
That is mostly what all of the "so what" comments are really about. What do you want us to do about it.
