From what you are saying a "traditionalist" is someone who will outlaw anything that harms the "public morality"?
the conservative "response" to these problems is to just outlaw them. That does nothing to solve a problem...it only pacifies your resolve to do anything constructive about them. It creates this attitude that since something is illegal it does not happen.
An active approach to pornography and abortion is needed. Children must be taught it is WRONG! They must be seen as threats to the individual not to the "public morality". Viewing things in terms of a group tends to make people less responsive (If I don't deal with it someone else will.)
Passing laws might make you feel good...but they do little. Individual minds must be changed.
As a libertarian I see there is no "one" response to abortion and pornography. Each individual situation must be dealt with.
If Abe Lincoln had felt this way, slavery would still be legal today.
