If a pro-gay democrat were caught having sex with a guy, it wouldn’t be terribly huge and newsworthy. But we have a lot of those stories when those anti-gay crusaders turn out to have their gay trysts. And those are notable for their blatant hypocrisy. The people who most warn against the dangers of homosexuality were actually repressed homosexuals. There’s a battle between pro and anti-gay rights groups, and it’s notable when someone at the head of one of those groups goes directly against their ideology.
However, there’s no pro-murder/anti-murder factions in our society. Murder is more or less incidental to any sort of ideological groupings we give ourselves, since there are no pro-murder ideological groupings. Murders (assuming they aren’t terroristic/political) are an individual failing, not the responsibility of a group that a person happens to incidentally be in.
If a Christian killed someone, would you start a thread with the title “A scummy Christian killed someone. What a shock”? Almost certainly not, because them killing something had nothing to do with their Christianity (assuming we’re not talking about an abortion clinic bomber or something)
Compare this, to, say, Sarah Brady buying an illegal gun and then shooting up a school. That would be noteworthy for its hypocrisy because she spent her whole life dedicated to banning guns. Her ideology in that case wasn’t some incidental belief that almost everyone holds (like child molesting/rape/murder is wrong), and it’s noteworthy that the most outspoken person against something did something.
“Family values” Republicans are mostly a codeword for being anti-gay, or censorship depending on the context. It has nothing to do with being against child molestation, anymore than it has anything to do with being anti-murder or pro-environmental conservation or any other incidental belief that some of its members might hold.
If Hastert kidnapped someone, we wouldn’t say “A scummy republican kidnapped somoeone, what a shock!”, and if Hastert got drunk and ran someone over, we wouldn’t say “a scummy republican killed someone while driving drunk!”, so why would we say “a scummy child-molesting republican, what a shock”?
You could still pit the guy as doing any of those things, but the attempt to paint him as a hypocrite like those anti-gay crusaders who get double penetrated in truck stop bathrooms falls flat, and the OP looks like a partisan idiot for trying to use child molestation as a way of attacking his opponent’s ideology, rather than one particular guy.
