Earlier quoted context omitted.
I worked for Bill for about a year at GV. He was one of the friendliest managers I've ever met at Google. I randomly met Dave Drummond once at a coffee shop in Sausalito (I didn't know who he was at the time... he just commented on my Google shirt), and he gave me an inexplicably uncomfortable feeling.
I think it is a bad idea to say this about him without providing a concrete example on how he made you uncomfortable. I'm sure I have accidentally made someone uncomfortable before. Does that make me a bad person? I hope not.
They don't have to justify themselves to you. He saw what he saw, and felt what he felt. if you have any problem with that, that's on you.
