The way men are viewed by feminism
It doesn't really matter what color you are. If you're a man you're guilty. Although in the ad colored men are demonstrated as less evil and occasionally the ones who "hold other men accountable", all men are innately flawed according to the feminist ideology.
Feminists can shout about quality as loud as they can but their actions show that ultimately they will blame men for simply being manly and they don't care about race, social status and sometimes even sexual orientation. So why should we be surprised that an ad created by a feminist attacks masculinity and manhood at its core and questions masculinity altogether?
What happens when men respond
Gillette basically took back their words and men forced them to do that. Although they didn't publicly admit that the change in their policies is caused by the backlash from their toxic masculinity ad, it's obvious they are afraid their losses would grow if they don't change their way and that's still good to hear.
What men can learn
We come from different backgrounds, we have different political and religious views but lots of men objected to the way Gillette portrayed masculinity and men. It wasn't just conservatives who boycotted Gillette. It was all MEN. We need to repeat that every time a media company or corporation of some sort decides to join forces with the man hating feminists and persecute manly men. This incident showed everyone in company boardrooms that men won't put up with everything, that men have purchasing power and they're willing to take their money somewhere else if they don't get the respect they want and guess what? Many companies changed their tone since the Gillette fiasco.
