The bottom line is: publicity.
He advocates for governmental execution of gays and lesbians in the US (1% of the population would mean 2 million executions. Now how likely is that, unless you are Hitler?)
When the Matthew Shepard thing happened, he did a stupid stunt where he acted out how McKinney should die - tied to a fence and beaten to death.
In that way, Enyart is able to show himself as innoccent - he advocates death to gays, but doesn't advocate citizens doing it - he wants the government to kill at least 2 million (there are actually much more than this.)
So, he shows outrage at the killers, supporting his death penalty for murder, and showing false empathy for Shephard. (After all, who, feeling empathy for the way that the Shephards must have felt, being told that their child was beaten so badly, they weren't sure if it was a scarecrow or human) would think that acting out a similar vengence on the accused would be of comfort to the family?
It was in poor taste. But anything for ratings, and that's the bottom line: publicity.
That's why Madonna kissed Britney - they wanted the press, they wanted publicity, so they did whatever they could, including shocking and offending people (instead of being admired for artistic ability) in order to get more fame.
But I've been on this board for a few years, and I barely know Bob, so anyone outside of this board probably doesn't know him at all, or just writes him off as a sensationalist.
