What you call a minor teenage girl is in fact a woman with over a year of driving, probably carries a .380 automatic or a 38 Special revolver in addition to a can of pepper spray, and already possesses more bearing and sophistication than many 30 year old men. At least that is what many 17 year-olds are like around here. Perhaps you live in a snowflake zone. So you insinuated all are just helpless little girls and thus insult them.
No 17 year old in the US is able to legally purchase a pistol or carry a concealed weapon. There are ZERO 17 year olds that legally do this.
