See...I don't see it as hate to call someone stupid, despite their education. Some of the stupidest people I know are lawyers...go figure.

Yes, it is hateful to wish someone dead or never born. I have not, thankfully, run into this sort of message or it would have disturbed me as well.
The comparison to Hitler. Bad taste...and ridiculous...I will agree with you. But hate? People make goofy comparisons all the time. Does comparing someone to Hitler automatically qualify as hate speech? I guess it could...depending on your personal view. Again, I come back to the shady nature of 527's that allows candidates or their campaign staff to be involved in sending these kinds of messages under the radar of campaign oversight.
You have somewhat of a point about the Kerry stance on allies. But I think his message (at least what I've gotten from it) is that he plans to seek out allies whereas the President has pretty much written off all allies...or at least it seems that way. And as long as the President is unwilling to bend on his opinions about allies, it makes no difference what anyone does to try to form alliances. The point being, President Bush is the one who turned his back on the allies when he did what he wanted without their consent (right or wrong)...so they aren't about to come back to ally status as long as he is President. Who knows if it's true or not?! I don't even know a single person in France...so I couldn't tell ya.
