I have respect for fighters, so no I wouldnt say anything, but Iwouldnt go out of my way to say hi and meet them.
I have Juan Manuel Lopez standing rightin front of me, and he was talking to people walking by, and joking around with people. I dindt even say hi, try to meet him, or even pay attention to his sorry ass.
My brother on the other hand, hates JaunMa, but still took a pic with him.
And this was before the Salido fights.
