The bolded statement is 100% wrong. I really can't speak for the MAGA gun nuts, but the "gang bangers" are not "too scared to go to war where people can shoot back". You are MUCH more likely to get killed as a gang banger, than as a US soldier. The US soldiers are better trained, have better support, better tech, etc by far than anyone they are going against. Gang Bangers are going to be going against people with similar tech on a regular basis. Which is significantly more dangerous than raiding an ISIS base. And when they aren't going against an equal level gang banger, they are severely out gunned, out manned, and out trained when they go against the police or anything like that.
