Do you think religious freedom should be limited in any way? (Why or Why not)
Only to the extent that is required to protect the fabric of society. So if you believe that a certain group of people need to be exterminated you don't get to go round killing them just because your religion says you should.
I'm cautious about the concept that national law trumps religious freedom in general because so many laws aren't about protecting the fabric of society. Rules against rape, murder etc are very different to, say, rules prohibiting consenting adults from gathering together because some people don't feel safe gathering.
