Religious freedom: I didn't know this was considered "traditional". The traditional value always seemed to be "think like me!". Religious Freedom is a no brainer.
Things that may destroy individuals/families/communities: I assume destroy means kill or cause serious problems in life to the point people cna no longer lively happily. Anything that does that to people should not be allowed, unless the person says "I'm going to do this, this is my purpose!" but that doesn't ever happen
Addictive drugs: See above.
I also believe in fedelity to some extent, but it depends on the couple. Generally, marriage is an agreement of total exclusiveness between two people. However, if these two people want to agree to have an "open marriage" where they can have other sexual partners if they desire as long as they are open and honest about it, thats cool too.
