It won't - but funny thing is you just keep putting enough stuff through and eventually you just keep moving the goal posts to the right.
Think about when we grew up there was not a single openly gay character on film and gays couldnt serve in the military. Now consider where we are today. That much lampooned slippery slope was a lot more slippery than we thought and now, every perversion is not only acceptable, its ADMIRABLE.
Even so, we should take a lesson from the gay lobby and their enormous success in obliterating our moral norms to get what they wanted. They would ask for 500% of what they expected, legislators and little old grannies would howl in the streets and much ruckus would ensue. When the dust settled, the gay lobby got maybe only 10-15% of what they asked for and conservatives went back to their cubby holes, smugly sure that they had beat off the barbarian horde. Then it happens again, with the same result. What the myopic rubes do not realize is that each wave goes further up the beach...until everything we knew is underwater.
Having been so successful and finally getting gay marriage ensconced, the problem is that the gay lobby machine still existed. Many gays went about their business but the progressive activists had to keep making a living so they fixated on the new thing and then promoted it into existence. A significant number of homosexuals now scratch their heads and even recoil in horror at the vast subversion of morality promulgated by the movement they and their sort, ignited - so depraved it has become in the name of "tolerance".
You may be sure that if we do not beat this back in some way, pedophilia will not only be an accepted thing in our lifetime, it will be lauded and praised as good for children.
