R=U is hated for many reasons, depending on the person.

For many, it is simply ridiculously in violation of parsimony.

For others, it simply would destroy the story as written.

Then there are those who think it's stupid.

Oh, and R&J is NOT a 'grand story of love, conquering evil'. It's a story about two romantic yutzes, one of them a preteen, who destroy their lives by rushing headlong into a wanna-romance without any gorram clue of what they were doing.
