Do Alan Keyes and Rush Limbaugh think everyone naturally wants to have sex with 7 and 8 year olds?

Both Rush Limbaugh and Alan Keyes (who knew Keyes was still alive?) are convinced that the Penn State child sex abuse scandal is really a "gay" scandal.  Which raises the question of why Limbaugh and Keyes are so convinced that a sexual attraction to seven year olds is based on your sexual orientation?  According to medical science, people who abuse children don't do it based on their sexual orientation.  But Limbaugh and Keyes seem convinced that the two are linked.  It reminds me of people who think being gay is a choice.  Sometimes I wonder if for them it is.
