Recognising that is not bashing.
OTOH, I will remember to ask anyone who is being raped, should I come upon it, whether they support RKBA. If the response is "no", I won't hesitate to allow the rapist to proceed. Guess that makes me a redneck, eh?
I didn't see any ethnic bashing, he was responding to the question of why some groups are less likely to accept conservative arguments than others. I think that you may have misread something, or perhaps I did.
In any case, I am a 2nd amendment backer who does not own a gun, so couldn't use some of the arguments he suggests. But much of the article discusses how to discuss any political issue with someone who is emotionally attached to the other side. For that reason I have bookmarked it. A lot of very nasty discussions around here by many of us would be more productive if we used some of these techniques.
