Not that I think the concert should have been cancelled. . .but isn’t asking for someone to be killed “spewing hatred”? Isn’t asking for them to actually be shot infringing on their “health and safety.” This is “if the shoe is on the other foot” example for me, it doesn’t appear that their ban was unjustified, or her ban was unjustified. Although, it probably doesn’t even really count because we are talking about two different countries here.
