Compare this reasoning:

Many or most teenagers are going to have sex whether we want them to or not, so, given the adverse consequences of ignorant or unprotected sex, we may as well (1) teach them about sex and (2) provide them with condoms.

With this reasoning:

Many or most teenagers are going to own guns eventually, so, given the adverse consequences of ignorant or careless gun usage, we may as well (1) teach them how to handle and shoot guns and (2) provide them with guns (so that they may become familiar with them).

The reasoning is analogous, so why do progressives have different attitudes toward sex education and gun education?
