” I’ve never met a prolifer who was packing heat.”
Even those who carry concealed weapons usually don’t tell anyone. They do exist, however.
“And in the practical sense, what would an armed prolifer do?”
Whatever he could.
“Spray the flaming-bottle lady’s car with bullets as she sped off and merged with traffic?”
Maybe.
A very poor plan. Likely very unwelcome by the prolifers themselves, high risk of harming bystanders, and little if any chance of either remedying the situation immediately at hand, or preventing future assaults against prolifers, who will in any case be framed and blamed as aggressors.
