1) you posting that not only carrying a gun, but taking it out whenever someone you see gets too close, then shooting them after a warning...is not only beyond the pale for discussion, it's advocating something that is illegal. you probably can be banned from DU for recommending people do things which are illegal, especially if they are violent actions.
2) calling out your post as nonsense does not make a person anti-gun, it makes them anti-nonsense, or anti-violence or whatever, but nice try.
3) being criticized for your idea doesn't make you a persecuted feminist, it makes you a person who advocated something dumb and illegal and someone who was criticized for advocating something dumb and illegal.
4) if you choose to stop posting in this group because an extremely bad idea you posted was criticized, then I'm pretty sure you seem a bit mislead on the purpose of internet discussion boards.
5) finally, when you post something as bad as you posted and then say, "oh but I'm a feminist!", reasonable people will question whether you truly are a feminist or perhaps a person who is attempting to make feminists look as dumb as the idea you posted while claiming to be one.
