Rgp, if that isn't pure racism loud and clear, I don't know what is.
And before you ask, yes, I am white and I often mingle with non-white people. My community is a beautiful mixture of races, ethnicities, etc. and, we often interact socially with those who aren't our own. Who cares?
The subject never seems to come up, at least not among the people I choose to spend my time with. And, to get back to your original statement, quoted above, I choose to avoid people who are consumed with hate and violence, who are doing their best to destroy what is good in this country. Most of them happen to be white. We all make our choices according to what is important to us.
And if all the non-white people you have ever met are so awful that you have to avoid them, it really does sound like you have to get out more! Trying to justify the murder of an innocent jogger because of his race demonstrates your own racism, and does nothing but stoke the fires of hatred and violence. It's hard to believe that you are actually boasting about it. But then, nothing should be hard to believe any more.
