Not sure if I understand what you're saying, but if I do, that's got to be offensive to at least two large groups of people.

At the end of the day, there are not just gay men, straight men and girls. Within the straight men there are subsets who equate a lot of social contact, gossip etc. with friendship, just as there are gay men or girls who don't equate this with friendship.

The "most guys I know of" thing is probably just confirmation bias based on social circles and career choices.
