Thanks for the response, windchime. So far, you're the only person to get back to me on this.
I already saw the article commending Regier that you point to in your post. The stance of the SHT is, though, unless I can come up with "proof" of the Miami Tribune hoax, my lead is a dead one. Again, no such standard exists for them.
I'm hoping to hell someone can throw me a bone here, otherwise I will just respond to them with what I have and move on. A lesson learned, and proof once again that we are engaged in a war of words with those who buy ink by the barrelfull.
I have no material that can help you with the "proof" you are seeking. Our local TV station reported Regier's denial of association with the group and controversial article, but they stated he could not produce a letter of resignation he had submitted to the group in the late 80's. Note to self: keep copies of resignation letters ...forever!
Your frustration is understandable. The following is the address for the Media Research Center.

You may already be familiar with the site. If you aren't, they expose media bias, primarily on the national level. I haven't seen anything on the Regier attacks, but seeing the bias in print might make you feel better. They even do a CyberAlert to keep you updated.
Hope someone has something you can use in your contact with SHT.
