Unhate?
From the warm up question: is love the solution to end hate?
Often, we like to think it is. If hate is returned to hate, isn't it only reciprocated? We tell ourselves then that we must treat hate with its opposite to cancel it out--love. But love is very rarely the opposite of hate. More often, it's the source of it. Because people love their religion, they choose to hate others'; because people love money and power, they hate people in their way or who have the things they think they want.
And in this unhate campaign, it's the love of certain beliefs that instigate hate between parties: the belief that homosexuality is bad, the belief that one religion is better than another, or the belief that one nation can invade another freely. The campaign was criticizing the hate that happens between world leaders; but what did they prove, or solve, by angering those leaders and their supporters? In this scenario, this company is acting merely as a rabble-rouser, not proposing a solution. I think they tried to make a dramatic statement about overcoming prejudice, drawing parallels of love as the solution or opposite of hate. The opposite, or solution to hate is not a kiss on the cheek, but understanding and tolerance--something much harder to achieve than an emotion as fleeting and extreme as love.
