I get why you would see someone calling it a joke and want to punish that because it was not funny and potentially dangerous.
But it can both be true that he was trying to make a joke, and that he was grossly irresponsible doing so.
You are telling me what i believe (that it wasnt a big deal) and im sorry but this reactive extrapolation of information that is constant and pervasive on sites like lemmy is something i hate and anyone can say im taking it too seriously but it keeps people from engaging/thinking instead of memeing.
