You did previously say:
But you seem to have shifted a bit to:If we are asking for governments to get involved in limiting the rights of religions to state their beliefs I would suggest we start with mainline theism.
We should not ban stupid ideas even if they are harmful.
You're right, you can't ban stupid ideas. You can't ban someone from believing that the earth is flat. But, as nuts as that idea is, by and large it doesn't harm people.
But should beliefs that cause harm be allowed to be preached?
As you stated above:
If we are asking for governments to get involved in limiting the rights of religions to state their beliefs...
If the teaching of hellfire to children warrants the 'limiting the rights of religion to state their beliefs' it's not unreasonable to apply that 'limiting...to state their beliefs' to teaching children that Gay people can change when that is a) not a view shared by the scientific community, and b) will cause a lot of harm to the children who will grow up gay or have gay parents.
