I like your spirit! But for to mollify the post-modernists, maybe severe flogging would be an acceptable compromise for a time. Til people get used to the idea of right and wrong.
That is strictly for the Gedolim to decide. I have nothing to do with deciding such things.
BTW, people still believe in right and wrong. They just believe it's right to practice homosexuality but wrong to eat meat. It isn't the concept of right and wrong itself that needs to be relearned but rather G-d's exclusive jurisdiction in defining which is which.
