How is Gary Bauer supposed to "discern" this? Racicot would not meet with just anyone and he knows it. He chose to meet with the HRC despite the fact that they are a hard-core pro-homosexual group that seeks to destroy the prevailing definition of the family.
The "I'll meet with anyone" is just a smokescreen, and Mr. Bauer correctly recognized it. The real issue is that Republican leaders are deeply uncomfortable defending the traditional family, because they have few if any principles in this area. This insecurity and a desperate desire to appear acceptable to the p.c. culture leads them to seek some level of acceptance from homosexuals.
How is Gary Bauer supposed to "discern" this? Well, it's true Bauer is a bit intellectually challenged to put it euphemistically, but he could discern this the same as most people capable of reasoning would. And he would presumably have an advantage in that he actually knows Marc Racicot and would have some insight as to whether he would meet with the KKK.
Bauer was obviously being disingenuous and hysterical. If you want to defend him as if he was being forthright and genuine, you only look as hysterical as he it.
