This is a widely circulated letter addressed to Laura Schlessinger, a conservative radio host and outspoken bigot (from what I gather. I'm not familiar with her but the few comments attributed to her that I have read were rather bigoted and idiotic).
Note: It is not at all clear whether or not this was actually written to Laura Schlessinger (the purported Dr. Laura in question) nor is it widely known who the original author was. Still, it's great stuff, so read on (assuming of course you have not come across this at one point or another).
Note 2: I have added a few italicized comments in brackets throughout.
Dear Dr. Laura:
