I think I see what you're going for here, but it's a dangerous argument to make. Someone's physical appearance should have no bearing on the validity of their opinion. An ugly opinion is ugly regardless of how attractive or unattractive the mouth it comes from.

Many of the racist, antisemetic marchers had strong chins, with square jaws. Many were tall, and muscular...the physical opposite of the picture you posted. Does that alter how acceptable we should find their statements?
