Sorry, you have to choose whether it's ok to legislate morality. I'd prefer to avoid it myself, but unfortunately I guess that's just another set of morals, right?
I agree with you in the sense that both parties are ideological in why they want certain laws passed. What's funny is that the topic is about "not politicizing non-scientific ideologies" when in all reality this is a political activist organization - and are politicizing science (or what they consider science, which is debatable)!
"Legislating Morality" is very much misunderstood, however. All laws have a moral basis. You just can't make people "moral" through laws. I heard a better phrase - "You can't legislate virtue"
