Doubt my opinion matters in the grand scheme of things, but -support.
It's one thing if he was to target the community's server(s) and call them trash. It's wholly different to state a dislike about the gamemode in general. This is like me saying I think TeamSpeak is trash (not our TeamSpeak, but the program in general) and getting shit for it. Don't know, the idea of there being a staff report because someone called a Garry's Mod gamemode "trash" seems nonsensical to me.
