It's actually really easy to tell who men truly love.
Just ask them to imagine the following scenario:
You and everyone around you have been slowly starving. There is now only one bowl of stew left and you are holding it. Person X is sitting next to you and is just as hungry, as you are.
Do you:
1) eat it quickly?
2) share it with X?
3) give X the bowl and encourage them the eat the entire thing?
That's indifference, alliance, love.
