It would make way more sense for Stargate cosplayers to be at a renfaire since every single planet they went to on that series seemed to have villagers at about the renaissance level of technology (gotta wonder, did they have access to a bunch of medieval/renaissance sets for cheap lol?).
Of course, if you went as Stargate cosplayers you would have to basically dress up as para military wannabe chuds who’s personalities revolve around owning useless guns (like sword person who is obsessed with swords but way less fun) and being a bigot. People might not even recognize you are in costume and just assume you are a bunch of losers who express their freedom by going to renfaires carrying around murder weapons and dressing in tactical gear.
I think they were saying the opposite. The gun obsessed military types you see in public may be bigots. SG characters may look similar bat are various races and not bigots.
