Can You See Where This is Going?

I recently read a story about how a couple ( from Norway or Sweden i think) could no longer foster children because they were serious Christians, and therefor would not approve of homosexuality. The child involved was not gay, and the couple had fostered a number of children before, quite successfully. At first glance i thought, hmmm well i suppose. On further reflection I have my doubts. For one thing, i thought we were supposed to tolerate gay behaviour, not accept or promote it necessarily.  Quite aside from that there is the question of where this sort of regulation could go.
   It isn't like our own little racism regarding fostering children. Here in Canada we try to foster certain kids according to race, on the assumption that... actually i can't even explain the logic other than : we are racist when it comes to natives. I think folks figure it isn't racism if you call it culture rather than race.
  No, the problem here is religious indoctrination, or as parents and sane people would call it: teaching our children. If the state wont lend a practicing Christian or Muslim a kid or two to foster because it doesn't like their beliefs that's one thing. One thing does lead to another however, and i wonder what 'another' might entail. Are we talking about  a future where the state prohibits parents from indoctrinating their kids into their religion?  Nah, that could never happen, except it already does in some places, like the USA for example. Of course we are talking about non traditional religions in the US case (wicca ) but I can certainly see the danger here. If a supposedly enlightened western state sees fit to regulate the beliefs of those people who care for wards of the state, it is only a matter of time before someone asks whether the same should not be done for all kids.
