They mention that because it emphasizes their other point.

It's the equivalent of "I'm a vegetarian but even I drool at the thought of bacon". You don't have to mention that you're vegetarian....it's there because it places extra emphasis on how appealing bacon can be.

sigh did I really to break it down like that

There's the other side of the coin though. You say that not to emphasise the point, but to protect yourself.

"I'm not a racist because I agree with x", don't call me a racist for disagreeing with you.

Sort of, was an "I don't have to be a racist to agree with X". Or "Hey, I'm on your side, but you did X poorly."

When a comment appears to a be a troll, is overly hostile, etc it's usually helpful to look at the account creation date and their posts history before bothering with a response.

Sometimes it's someone with a varied history burning karma for a topic they are passionate about, but in this posters history it's obviously not.
