This comment is on par with those that seek to reduce abortions by banning them. In both cases, you have absolute positions “no guns”, “no abortions” that ignore the fact that people have decided they need these things and are going to get them. Similarly, those positions ignore real, practical steps, that help address the underlying issues.
The smarter thing for reducing abortions would be free contraceptives.
The smarter thing for reducing gun violence (when it’s accidental) is absolutely what the other person here said, train people how to use them properly and safely.
