What can we do? Men are **** and are genetically programmed to lust after young women to bear their children. It's nature, and regardless of how much we disapprove, it's no big surprise when it happens.
Look at someone like Mick Jagger in his 70's still knocking up 20 year olds. He's a rock start and will forever sleep with 20 year olds, fact of life.
Trudeau was like a rock star in his own way and he had women swooning over him. I can't blame him for hooking up with Margaret but the key point is that their relationship was consensual like Mick Jagger's.
You can't compare it to someone who can't take no for an answer and persistently shows unwanted attention. Big difference.
