That's kind of my view in general. I rarely resort to calling my opponents stupid. Glass houses/stones type thing. Many of the people (not saying XX is like that) I see on-line calling Bush "idiot" or other such names are barely literate.
You should see some of the email I get from people who can barely put a sentence together yet still feel confident in calling Bush a "moron". Or better yet, those who consider Bush supporters "stupid" while they themselves care barely write.
