This is my favorite line in the website:
They were saying that if you want go by Leviticus-you better be ready to follow all the laws. Then they said:
"This includes not only the injunction against shellfish and mussels and such, but also against wearing fabrics made of blended fibers, cutting or shaving your beard, sowing mixed seed in a field, and a slew of other things nobody but Orthodox Jews take seriously anymore."
(bold mine)
They're right. It is an abomination to eat shrimp. But only for Jews. Not for gentiles. Homosexuality is a violation for both Jew and gentile.
