Expressing disagreement with someone involves saying, in some form or other "I think you are wrong." That is criticism, and it's of a person, thus it's personal criticism. Perhaps we're using different definitions of "criticise"? (In addition to different spellings ;))
I think it's more likely that we're using different definitions of "personal."
If you believe I'm using the wrong definition of "personal" or "criticize," please be assured that I don't take it as a personal criticism.
