Sure, and I'm not arguing with you, merely giving a perspective that perhaps going with the group doesn't always get you what you want. If you value using a given OS more than playing a certain set of games with friends, that's an absolutely fine take. There are lots of options between the extremes of "don't play MP games at all" and "only use Windows for gaming."
If you don't want to play a specific game for some reason, don't play that game, even if all of your friends try to force you to.
