It wasn't an insult at all. Plenty of ways to phrase what I said as an insult, and I used none of them. I was pointing out that: (1) you didn't seem to know what terms meant, and thus (2) were using that as reason to assume the other person is a troll.

I'm not defending the other person either, I just get annoyed when I see people assume everyone is trolling simply because they're offering a contrasting opinion on something. If someone really is trolling, it shouldn't be hard to point to why you think that.
