Right! I went and read various journal sources on the scandal and its progress. I'll see what I can remember...as my browser just reset and I lost my post.
It would be fairly easy to suspect a "conspiracy type theory" of sorts regarding his recent relevation of homosexuality and alcoholism, as this may be playing the 'anti-discrimination backlash' card. On the other hand, it could be a genuinely forced play, and the declaration of shame could be a significant factor. In fact, I'm willing to say that it is, but how significant compared to everything else remains to be seen.
At the root of this however, seem to be two justified causes of outrage: As Palefrost (and Bush) point out, his actions do constitute inappropriate conduct, and that he did this in a public post means that his actions also constitute a breach of trust/abuse of power. As soon as they became apparent, I would have thought it appropriate to review his position, and grounds for call to resignation would be if it were further apparent that his behavior was not manageable. I would be interested further to know why Dennis (House of reps) acted how he did, obviously as it would shed some light on whether calls for him to resign are justified.
Amongst various editorials, I see some misconceptions. First, fellow Republicans are shocked at this because Foley was apparently a staunch anti child abuse and anti child pornography campaigner. The shock would typically come from percieving that he was being hypocritical (as I've seen), but this judgment is far too hasty, as upon closer examination, the two may not be related (just as confessions of alcoholism and homosexuality may not be directly related either).
Of clinical significance is the fact that Foley's conduct is not defined as pedophilia so much as perhaps ehebophilia (attraction to young, but not pre-pubescent people). The etiology of this can be quite different, but I obviously can't run a psych assessment on Foley from behind my desk in Australia!
Basically all I'm saying there is that while it is inappropriate to judge in the first place, it is even more inappropriate to judge Foley as a pedophile as it is likely inaccurate. I do agree with Todd's line of thought here- discussion of the relevance of events along a developmental timeline and their influence on behavior as opposed to congenital predilection is a tricky thing and would require more personal information that I suspect we will not be privy to.
