I'm just curious as to why I'm being laughed at

Because your ideology clouds your ability to make factual statements. Rather than present facts, you spout lies conforming to leftist agendas. It's humorous seeing an expert lie so blatantly or someone who is so stupid and displaying it.

Fun fact: Not only can you tell the difference between a female and male skeleton, you can also determine the RACE.

They should have their "PHD" revoked for intentionally lying in their profession and attempting to mislead people that should be considering him an expert. If nothing else it makes the place he got his PHD from look brain damaged.
