When someone says “With all due respect…”, they’ll inevitably follow it with an insult. In that case, the person is therefore also implying that the recipient is due NO respect since they’re insulting them. Boom, double-roast. Maybe obvious, but apparently not to me… with all due respect to me.
I don’t know who you talk with but “with all due respect” is followed by disagreeing with something you said. Not an insult. The disagreement could be dissmissive of your previous argument like “thats bullshit” which gets pretty close to an insult but its really just poor argumentation on their part. The problem is not with the phrase “with all due respect” its with the individual using it.
I agree, with all due respect
