I kind of see it as there being people who play video games and “gamers”. The latter being people for whom gaming is a serious hobby they care about a lot. Then there is a subset of gamers (sometimes referred to as “Gamers” with a capital G) that are also shitty people who take it personally if there is any kind of minority representation in video games and are the people who call you slurs in multiplayer games either for not being good enough at the game or or being better at the game than them (depending on whether you are on their team or playing against them).
