Edit: For clarity, the "you" used here is the collective you and not "you" as in the account I'm replying to.

For the record, I agree with your example and personally won't eat/buy The Lord's Chicken™. But do you really think you've changed anyone's mind? Probably not. All you've accomplished is making yourself feel morally superior. You don't like something? Fine, more power to you. Don't buy/support the thing (you should see the ever-growing list of companies and subsidiaries I won't buy from). But also don't slide into the DMs of other people's lives and shit all over what little brings them joy. Why is this hard?
