I knew someone who habitually began sentences this way and let’s just say you wouldn’t want to do business with her. Using “if” in an apology implies that you didn’t actually do anything wrong and you’re having to apologize because the person you’re speaking to is thin-skinned. If you don’t feel you have something to apologize for, don’t apologize. If you said or did something you shouldn’t have, own up to it. The word “if” often negates whatever came before it.

If you’re speaking with someone who has compromised your respect then this is insincere.

If you’re speaking with someone you respect you should treat him/her as an adult and speak directly. If you’re actually a sincere person you don’t need to pepper your language with words like “sincerely,” “honestly” and “frankly.” Believe! Whatever the case, saying “no offense” makes you sound like both a sissy and a jerk. Sometimes you should just keep your mouth shut. If you feel that you have to share an opinion that might not be well received, don’t be a wimp about it. Say it without apology. On the other hand, if you feel the need to preface something with “No offense,” maybe you shouldn’t be saying it. Don’t be a jerk. Sometimes a situation calls for you to be obnoxiously assertive. Either take ownership of it or don’t say it. Don’t use them unless you want to trigger people. Some of the best evidence of this is how frequently we resort to the following phrases.

People tend to underestimate one another’s bullshit detectors and overestimate their own.
