When an apology begins w/the word "if", the apology is insincere. "If I offended anyone...blah blah blah..." Yes, you have offended someone because they just told you that you did! The proper apology would sound something like "I have offended ________ and for this, I am sorry and do humbly apologize". No if about it. Politicians, especially, "if" w/us enough as it is.
