Isn't the way to stop discrimination to stop discriminating?

I've seen several answers today that attempt to justify discrimination against men. It seems ironic to me that it seems to be those who claim to oppose discrimination are also the ones who actively push for it. It seems to me that as long as we support policies that discriminate, we will have discrimination. It seems to me the way to move away from discrimination is to get rid of discriminatory policies in favor of equal opportunity. What's your perspective?
