If Shep is or isn't, I don't really give a rat's behind. I suspect the source's motives, however, and I don't much care for their tactics. I'm wondering if this is nothing more than an attempt to smear a known conservative, and include a (known?) gay anchor to try to give their assertion credibility.
Stealth tactic to undermine Fox News' base. They can't attack them directly because FNC is more accurate than CBS, etc., so an attack against the most popular anchor with something they think will offend his base is the next best thing.
