M and I just had a really good conversation about this (not about the fake apology). I also do not think his apology was adequate, and I thought ...well, a lot of stuff, which was crystallized during our debate (we do that a lot) but yeah. I mostly agree with you here.

My pet peeve with apologies is mainly centered around phrasing such as:

I'm sorry IF I blah blah.

Like, clearly if my feelings are hurt, you DID BLAH BLAH. Say, "I'm sorry THAT I blah blah" and it instantly sounds more sincere. Your peeve sounds a touch different, but I get it. =)
