I see two streams of thought in this argument:
1) He's at worst a closet racist, at best delinquent in management by allowing these articles to be published.
2) He doesn't know who wrote them, and he didn't write them--so who cares?
I'd like to offer a third, that, to me, appears to be completely absent in all discussion.
The articles themselves, while distasteful, are neither racist, homophobic, or anti-semitic.
The articles on the LA riots aren't racist. They're harsh, but neither racist or false. If people can't deal with it, it's not Ron's place to apologize for hurting their feelings--regardless of who wrote it.
The David Duke article does not praise David Duke. It argues that Duke was able to garner 9% of the black vote running on the platform of individual liberty despite his background, and questions what it was that allowed an admitted KKK member to get that many votes from black voters--concluding that the liberty message is powerful enough to overcome even Duke's serious issues to get a reasonable amount of minority vote. It is not a praise of Duke--it is a praise of the liberty message using Duke to make the point as to how powerful it is.
The MLK articles (not in Ron's writing style from what I've seen of it) is very harsh, but apparently true as well. The data offered appears to be pointing to another author's work (that author being a black man who outs this info.) The article is also an argument of voting against a federal holiday for King--which, FWIW, is no longer celebrated at the corporation I work for since being purchased by the Brits. (I guess you don't have to worry about not honoring King's holiday if you aren't a US company as it can't be used in the squealing points.)
The articles on staying in the closet just appear to be ranting decrying the need for homosexuals to proudly proclaim their orientation to all. Where I live, there is a fairly large football homecoming parade yearly that always has a gay pride float where the participants are often clad in leather chest straps and chaps, dirty dancing and making out with their partners for shock value. Simultaneously, the streets are usually lined with parents with small children. (Adults don't watch parades by and large.) Now, I don't give a sh!t who you sleep with, love, or want to marry (hell marriage is financial trap in the modern era anyway, and if gays get state-backed marriage, they may come to regret it)--but no parent should have to answer a lot of questions from a 5-6 year old after seeing a float like this when no other float's parade participants feel the need to act this way in what is designed as a family atmosphere.
As to the anti-semitism, being against the Israel lobby in Washington is in no way anti-semitic period.
I guess my point is this:
We are buying into a two-pronged smokescreen whereby we are now correctly defending Paul against the attacks, but missing the point that the attacks have been framed to generate dissent due to matters of taste--not factual -isms.
Top that off with the blatancy of some posters who are here to stir the sh!t in a "sympathetic" manner, and you have what I am now witnessing.
It's a facade! The whole argument!
Hell, if I knew the authors, I wouldn't out them either in the face of a bullsh!t scandal.
I'm done now.
