Yeah - there are Log Cabin Republicans too. If David Westerfield voted GOP, so what? While we appreciate their votes, doesn't mean they are moral in the rest of their lives.
I'm not saying people who go to sex clubs are moral people. I'm also not saying they're inherently IMmoral just because they go to sex clubs. My point is that I really, really don't care about how they get their rocks off, and that the entire question is entirely tangential to morality.
Likewise, there's nothing inherently moral or immoral about voting GOP. (Perhaps there may be something inherently IMmoral about voting Dem, but that's a different topic). Mr. Westerfield is not an inherently good person for voting GOP, nor is he an inherently bad person for attending a sex club. He IS an inherently bad person for kidnapping, raping, and killing a seven-year-old girl. Once again, this really isn't complicated.
