I suppose my language was imprecise, let me take another go at it. A felon loses his right to mount a self defense as effective as that allowed to the general public, over the age of 18. Ok, I think I covered my bases there :-)
the word effective is subjective. people with knives, hammers, other non-gun tuff, kill people with guns all the time. the tueller drill? surprise attacks?
so the answer is still yes.
my sympathy level for convicted felons that used violence and weapons in their crimes, that they lose their gun rights forever, is right there at zero and’i do not give a damn they can’t have guns anymore. they are lucky society did not execute them. train robbers were executed regardless if anyone was murdered. horse theives were executed for taking someones horse and leaving them stranded regardless they did not blatantly shoot someone. they are lucky to be alive.
