Here’s the story I found with this picture by M. Lambrechts:

This meeting happened at a Gay Pride event in Brussels, Belgium in 2009. The child is the son of a gay couple attending the event and he got curious about this punk’s spiked jacket. So he went over and asked whether he could touch the spikes as he wanted to check whether they’re sharp or not. To give him better access, the punker knelt down and talked to him, amused by the kid’s reactions. When the two dads called their son back to them, the boy gave the punk a little kiss before returning to his fathers.

Just one little picture doing away with a multitude of prejudices.
