And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he unclean to you. Of their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you
And as for the Frog Legs:
And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you
So you won't allow 2 people in love to marry because they are of the same sex and some old testament scripture said so and yet you would suggest to eat pig or frog even though the same old testament scripture forbads you.
