And can I choose my own culture? Like say "this is what I endorse and believe in" and that be my culture? Or does this only apply to policically registered "-ism" classes (race, religion etc)? If so, I belong to the culture that considers it insensitive to shit on things for light-hearted naming themes as if they are of any relevance next to a million other adoption metrics that are more objective, assuming the author even cares to weigh adoption vs creative license in the first place.
