Really? If a male walked round with his bollocks hanging out half the time - he'd be decried as either a creep, a criminal or at least a perv.
Also, Trump was (rightly) shamed for claiming to grab women by the pussy. He did not offer to lick people out if they voted for him - which is the equivalent of what Madonna said. Nor does he parade around getting his kit off at every opportunity - or forcibly french-kiss people against their will (Drake). Can you imagine? A man would be arrested for that. A woman would not.
He does, however, do that thing of having trophy partners several decades his junior - and it's just as creepy when he does it, as when she does. It's not ageism - it's the fact that it's inappropriate and unstable for your kids, and shows a tendency to put oneself first (as Trump and Madge both do), and also slightly taking advantage of the younger person. Altho... at a basic level it can be seen as a transaction - Madge & Trump buy fresh meat in return for what their partners require, which is money and reflected fame.
No males have been called sluts or skanks? Anthony Wiener has - and rightly so. However, he exposes himself less frequently than Madonna, and basically ruined his career over it. It made hers. Another, less popularly accepted form of sexism?
I'm disappointed by both Madonna and Trump - and for the record, I'm not right wing. Despite Madonna's talents, intellect and savvy, she does display a worrying habit of hitting out at anyone or anything who disapproves of her, or stops her putting herself first and getting what she wants. Sometimes she's right, sometimes not - but she's consistently selfish.
The latest one? 'Why can't I maintain my popularity at my age, and also behave however the hell I like, and grab everything I want, with no recourse to how it affects anyone else?' Well, you can - but don't expect to escape criticism for it, and don't bother blaming it on ageism, or misogyny, or whatever the hell else trips off the tongue lightly.
