Your 140-Character Shaming Campaign is Weak
Shaming doesn't accomplish what you think it does. I mean, sure, it makes you feel like you're part of some sort of solution—the internet tribal equivalent to the end of Game of Thrones where the evil woman (I don't watch the show) is stripped naked and has to endure taunts and vegetation thrown at her. It does not, however, move things forward in any real way.
Christmas is a time for giving, being with family and friends, and hating every other asshole out there in the shops and on the roads also trying to spread joy and share in the Christmas spirit. Similarly, Hanukkah is a time for Jewish people to desperately try to feel relevant during Christmastime.
