I have my beliefs and you have your beliefs. As a stereotypical blogger writing from my parents’ basement (full disclosure), I’m probably not going to convince you to change your beliefs, nor do I think it’s my business. But can advertising? We already know that advertising can cause people to buy things they wouldn’t otherwise. But can it change core beliefs? This extremely well-done video for marriage equality from Get Up!, an Australian advocacy group, might just have that power.
