Part of the purpose of debate is to find the holes in an argument so you can fix them. If you don’t understand your weaknesses, you can’t guard against them. That is why people play devil’s advocate.
Especially when your argument is as full of holes as ‘some corporations do horrible things, so clearly making implications about an evil corporation, no matter how wrong, is the right thing to do’.
If you think that’ll stop them, I have a bridge to sell you. In case you hadn’t noticed, the law doesn’t mean anything any more to the people in power.
