Yes, and rap singers refer to themselves with the "n-word".  Does that mean it's an acceptable, non-perjorative term now, and we are free to use it on Wikipedia to describe Al Sharpton and Barak Obama?  How about the members of the gay community who call themselves "f-word hags" and such?  See how silly your own arguments sound when used against you?

 Furthermore, you cite Buchanan and Buckley, both of which use "neo-conservative" in a perjorative sense.  Thank you for citing evidence to prove MY point.  By the way, who is Douglas Murray and why does his opinion hold so much weight?

 Neo = new.  So, Mark Levin, who has worked for a Republican administration over 20 years ago and has been a conservative for as long as anyone can remember...he's a NEW conservative?  

 So, either come up with a better defence for this obviously perjorative term or I'll scrub it.  Levin doesn't label himself "neo-conservative"...which I think should be the real test of this term.
