So, by extension:  "If you feel that shooting someone in a drive-by is murder, don't do it, but for the love of all things holy don't push your values down other people's throats." First of all, we oppose murder because human life is holy, given from God.  And it is necessary that murder be forbidden in order for all human beings to have the life that God gave them.  Normalizing murder is not even remotely libertarian.
