@coldjoint,
It was only a matter of time and it won't stop with this.
I wager that with all the extreme animal rights activists, pedophilia will go "mainstream" long before bestiality.
I'm pretty sure that very few (if any) of our progressive members are OK with this attempt to normalize a sexual perversion that harms children, and that none, who may be, will admit to it.
It seems like a much bigger leap to make than supporting same-sex marriage, but keep in mind that that taboo was very powerful for a very long time; so much so that Democrat politicians like Obama and Clinton had to experience an evolution of thinking in order to remain in step with their base.
The route it will take is to first, fully "recognize" the sexuality of minors. We're half-way there with the recognition of homosexuality and trans-genderism in minors. The next step will be to argue that statutory age limitations are arbitrary and infringe upon the rights of
sexually aware minors. From there it's just a matter of lowering social restraints on supposedly consensual sex between an "adult attracted minor" and a "minor-attracted adult"
It may prove to be a bridge too far for moral relativists to cross, but the effort will be made.
