German = someone born in germany what part of that should make a german feel ashamed in 1946? Oh i don't know maybe the whole thing about death camps.
Yes gamer = someone who plays games. just like german = Someone born in germany. Not all Germans kill people in death camps not all germans agreed with it but it is not unreasonable for the nation to feel a collective sense of shame for the minority of germans that committed ethnic cleansing and genocide. Germany went through a collective sense of shame and grieving for what they did as a nation.
Gamers should also have a collective sense of shame that within our ranks people can do not only deplorable things but can be celebrated for doing said things. That people can make murderous threats and the collective result is the vast majority go "Meh. It happens whats the big deal?" Oh i don't know the big deal is it shouldn't be acceptable to make threats like those just because you disagree with a position. This behaviour isn't confined to targetting feminists, there is a case of a player on EvE online who publically stated he want to harrass another player and called other players "to arms" for the purpose of harassing a player so badly that they would kill themselves. That was his stated goal to make someones life in a game so miserable the killed themselves. (The person did not kill themselves to be clear). This type of vile behaviour is not an issolated case, it might be a minority but we the majority allow it the exist.
I disagree that an individual should necessarily have to feel any guild because of a label thrown onto them regardless of their actions. I do think people should make an individual and collective effort to stamp out these mentalities, just like how many workplaces would fire a person for something racist or sexist or discriminating in any way, and online games will perm-ban players for such things.
If I see someone saying racism or sexist slurs in a game I'm not obligated to stop it because I'm a gamer and I don't like the images of gamers being slandered, I'm obligated because I want to be a decent human being because I understand the value a society has in not allowing that mentality to fester.
