You want a why? Because AH is a GAME not a dame romance room.
I think it is a fine game, and a fine simulator, and being such, should strive to simulate more about flying.
Now, anybody that thinks that meeting people of common interest over drinks and perhaps some discussions of gay rights and abortion is not a legitimate part of being a pilot is, well, not very realistic.
Pilots want to meet people of common interest over drinks, and sometimes, just sometimes, they would prefer to do so in an environment of simulated air-combat.
You don't have to discuss gay rights if you don't want to, just don't be a racist and stop others from doing so.
