Rand, this is already happening... Kindergarden children are even being taught they can choose the gender they wish to be. Perhaps yourself and other posters here are not aware of the Radical Homosexual Agenda. Christian preachers have already been fined and gaoled for "discriminating" by teaching the word of God regarding homosexual activity. Adoption agencies have been legally forced to close for refusing to facilitate adoption of the children in their care to same sex couples. Bakers / shop keepers who refuse to provide wedding cakes and rainbow cakes for same sex celebrations, providers of other wedding services, providers of accommodations... have been taken to court, fined, and had their businesses closed. On the agenda is an attempt to force Christian Churches to preform same sex marriages or take the consequences of refusing to do so. These are the real agendas of the push for same sex marriage and just some examples of how law can be used under the guise of "discrimination".
But this is not the thread for further discussion on these matters.
