In the US here, Madison Square Garden now has a policy of "no shot, no entry" basically, which means you can't attend any event without proof of a vaccine. This is a very dangerous path as far as I am concerned. This is a path toward segregation of the population which definitely rubs me the wrong way. I hope other venues choose differently.
Segregation? Between those who chose to have the vaccine, and the anti-vaccine muppets. Bring it on. Frankly, if ejecting them from the planet was an option, I'd go for that.
