why you taking this personally. I said theres nothing wrong with what the shooter did. Guns been saving the weaker man since they were invented. As you said, its why they were invented; its the great equalizer in terms of violence because there are no rules in the real world.
But we are not going to sit here and say pulling out a gun on another man who's offering you the fade with his fists up is anything but p*ssy shyt. That shyt wouldn't fly in any culture in any time period but modern society. As most likely know, shooting unarmed men is routinely excused in our society.
Stupid? Arguably. Toxic? Definitely. Fighting a another man on as equal terms as possible is staple in masculinity. Weight classes in combat sports exist for this very reason. And I never expect fair ones from ppl outside of the gym. Most are built to actually take a punch let alone lose a fight.
