Sometimes in forums, when someone says something is bad, someone else argues against them calling it bad because it would be hard to make that something illegal, despite nothing about legality having been said. It's a frustrating argument because it implies laws are the only moral standards one should adhere to, and it disregards any possibilities between something being good and 100% legal or bad and 100% illegal. Usually I downvote that kind of response because it just encourages a polarized discussion that embraces a false dichotomy. ngold's post was ambiguous about whether he expects meat production to become illegal, so I don't think you were wrong to bring legality into the picture and I didn't downvote you, but I can see how someone could think your reply fit the above pattern.
