You should be careful with the use of "with due respects" or "with all due respects".
It, in my mind, connotes a willful disagreement with someone in a position of authority.
Police officer: "Madam, I just saw you pick that man's pocket."
Woman: "With all due respects, officer, I think it is time you visit your optician."
The addition of "with all due respects" does not substantially reduce the insolence of the woman's response. It would not shield her from the officer's anger.
So, if the comment is likely to cause someone to be annoyed or angry without the "with all due respects", it probably will continue to do so with it. The phrase does not substantially mitigate the damage.
