I did not call you stupid, I asked if you were playing stupid. You do see this difference, yes?
A race is a group of people who share the same race.
A member of race xxx kills someone.
Someone says that xxx race are killers.
This is not a fair statement, right?
Your quote: “Trump supporter went on a mass killing spree and your side's only solution is to arm more of them.”
Insert any race of your chosing in place of “Trump supporter”, and see if you are not considered a racist by the offended race, as well as other races.
The concept I’m trying to relate is you a using the same technique tgat racists do to disparage a group of people: the actions of one bad member represents the whole group.
