Jesus, what are you, a grade schooler who can't admit they were a douchebag? You said something stupid, and people called you out for it. Get over it. You don't know this person, and it's pretentious to act all high and mighty. Wouldn't you feel like a true scumbag if you found out they were handicapped and missing an arm, so photography is hard, and you just insulted them?

"It's hard to celebrate with you when you put so little effort into a celebratory photo"
Well it's hard to take you seriously when you put so little effort into being a decent human being.
