It's not really that, more like nobody cares what you personally wear unless it affects them. Ie:
If you party with someone wearing bad choices of equipment, you infringe on THEIR time and they will probably complain.
If you claim X is > than Y if in truth Y is > X then you will be corrected, further contradiction will cause people to bash you
Edit: Misinforming players with poor knowledge about the game, nobody likes seeing this
Remember, it's a community game, if your "playstyle" hinders another player, they will let you know.
