Shouldn't we oppose the silly ones? Is banning pot while (mostly) allowing alcohol valid or silly?
Their whimsey or seriousness notwithstanding, they are the law and we are not allowed to pick and choose which laws we will and won't obey without consequence.
Straw man; nobody here has claimed otherwise.
As to my "straw man" - I was under the impression that there are many who decide certain laws are silly and proceed to ignore them. Are you telling me that among those who argue in favor of legalizing certain drugs, there isn't a certain number, possibly a majority, who use those drugs themselves and wish to have the law changed so they can continue to do so without the threat of prosecution?
