Most M3 owners will say no. I will say no. But not that I think people are posing with an M3 badge. But because of the elitist mentality of many an M3 owner. If someone wants to put on an M3 badge, go for it.. What that does is turn on a switch in my head about the person. That image is more important than anything else.
I love it when people ask me what year my M3 is. I say "Oh this isn't an M3, mine is much faster"
