Some people only have the "courage" to insult others over the internet, so I doubt he would ever say it to your face.
Yeah, I know the type. I once foolishly agreed to meet a guy from local bulletin board (pre-internet) years and years ago to hash out our differences. He ran.
Older and wiser, I wouldn't do it again. A good way to get shot. If not by the guy you went to meet, then by his buddy hiding behind the dumpster you didn't see.
