There is zero truth in judging someone based on appearances. I'm pretty sure black people alone validate that argument.Still the truth.
Is he a good teacher? Is he smart? Articulate? Respectful?
Just because someone disagrees with his choice to ink up doesn't take away human decency and respect in this country. I'm sorry you seem to want to judge people by their looks, but that's not how normal, polite, decent society works in real life.
