Everything you say is true, however in Madonna's case she shoots herself in the foot repeatedly when she makes accusations of ageism and then uses filters on her photos. It's quite simple why she gets the abuse, because she invites it. If she was proud of who she was she wouldn't fake everything, that's one of the most disappointing things about her these past few years. She could've absolutely carried on without surgery and still looked amazing, now she's done so much weird stuff to her face and body she looks horrific without filters (and that's nothing to do with her age, that's just a series of bad choices).
