Way to end your career early you asshat!
73 year old Roger Waters' career is ending early, is it?
And all because he calls out a scumbag when he sees one?
This is something he's been doing for decades (including every concert I've ever seen him at and I've been to several).
Perhaps you should get in touch with Roger and tell him his career is ending early because of this long-established behaviour.
On the other hand and far more likely, perhaps his career isn't ending at all and certainly not because a couple of ignorant* fans booed him at a concert.
Roger Waters' career won't end until he either retires of his own accord or dies.
*Ignorant of Waters' well-documented views on Trump, some of which have previously been discussed on here.
-EDIT-
He also thinks Clinton is a scumbag but if she'd won and it was her he was lampooning (which he almost certainly would have done), I doubt Breitbart (or you, for that matter) would be getting their knickers in a twist about it.
