PG, unfortunately, calling attention to suspected socks in good faith doesn't seem to be a personal attack.  (See generally WP:SOCK) (But don't run around accusing everyone of being socks themselves, or you'll get yourself spanked for violating WP:POINT!!!).  I am not crazy about it, but I don't think it's nearly as offensive as calling someone a rapist, for example.  Even more confusingly, there isn't actually any rule against using socks, as long as you don't vote twice on the same issue or do one of a few other forbidden things.  My advice would be to blow the whole issue off  your comment counts as much as anyone else's, whether or not someone called you a sock.  Just explain that you're not a sock and go back to making your edits  what do you care what some other random editor sitting in his basement (like me) thinks?
