Why is Neil de Grasse Tyson popular? He's a bloated blowhard, obviously he is handsy with women He's not really a scientist anymore, he runs a museum.

@Alyosha “How does his weight have any bearing on his value as a scientist?”

Appearance has bearing on a lot of things. Do you listen to scientists with rainbow hair? What about scientists who look like they are starving? You would be too busy looking at their gaunt face to listen to what they say. Reading the works of a faceless author is better. The best authors are those we never got to see on TV.
