Our reading
An editorial interpretation.
This is an apology with a caveat attached. The speaker keeps the belief that started it all but admits that believing something doesn't make the damage okay. Saying sorry to a parent for ruining their cookout, while not abandoning the cause, is the sincere and slightly awkward part.
