Just like having to prove your age to buy liquor you should have to prove your vaccination before being allowed into any public gathering.
Know what would be easier? Putting a tattoo on everyone who hasn't been vaccinated. That way they could be identified right away. Considering the grave danger they pose to all life on earth, maybe they should also be put into special areas to keep them away from everyone else. If necessary, we could build some sort of fence all around this area.
How's that sound, you fucking nazi? Scumbag democrats never change.
