Cafe Charges Men more in response to Gender Pay Gap

We are going to talk about this in a future post. But let me pose some questions that come to mind.

Is the gender pay gap the effect of men being different from women in important ways?
If it is, then is it unfair that men get paid more than women?
Is discrimination the right solution to discrimination?
If some men discriminate and some men are discriminated for, does that mean all men should pay the price?
Is it in the cafe owners rights to discriminate against men?
Is there a double standard for conservatives who aren't allowed to discriminate against gay people, and liberals are allowed to discriminate against men?
