I go to concerts to hear music.
If the perfomer starts ranting about politics (of any kind) I start screaming “Shut up and play” at the top of my lungs. Very often others will join in.
It is quite fun.
But what do you do in Mad Donna’s case? Her talent is basically missing. I think she would be more entertaining seeing her spew political nonsense. Besides, seeing that aging slut strut herself nude on stage is probably more than anyone can stomach.
