Just because we disagree with someone, and feel offended by what they say, that doesn't really justify calling it "offensive". Otherwise there wouldn't be an opinion on anything that wasn't "offensive", because just about anything you say can get up someone's nose.

"Good morning" "How dare you say good morning. My wife has just left me."

"I blame it on Margaret Thatcher." "Mrs Thatcher is my hero. I find that remark deeply offensive."
