Maybe the GP did engage in the naturalistic fallacy, but nobody has been able to demonstrate why eating meat is wrong either, they just say "I personally feel killing animals to eat them is so evil that it should be illegal." OK, that's fine, but why should I also feel that way? I don't.

There's no fallacy there. There is nothing wrong with eating meat and writing that this a perfectly acceptable and natural behaviour is just stating a fact, really.

This is all proving my point that a vocal minority is poisoning the issue in order to impose their views by accusing others of fallacy, wrongthink, and even according to the person you're replying to (and that's a new one) by bringing rape into it...
