Yes. This one is going to be much trickier to argue.
There is obviously a limit to religious freedom already, but it's way out in the "obvious" category. For example, if your religion involves having you murder random neighbors it would not be tolerated even under the auspices of "religious freedom". But finding where that line is actually drawn is going to be much harder to nail down.
