they've been here in the past. Like you, if I can understand the thought, I don't make a big deal about the spelling. If I can't, then I ask for clarification, not point out the error in a manner that would presuppose superiority. But when I make the error, I do want to acknowledge that I know that I know the difference (and I blame it on the spell check in any case).
I think you've done Crazy Harry a disservice. He blows things up but he usually asks did someone say to blow up ... Bill Ayres just blew up public buildings because he didn't like the powers that be, I'd also bet he would be the first to criticize anyone who did similarly today.
