No. Having someone DEMAND that you show private medical information to enter a government operated/regulated public event is a violation of civil liberties.Taking a covid test is surrendering your civil liberties? The horror.
It also makes no sense whatsoever. If you believe in the vaccines and take it then you have no reason to fear an unvaccinated person, right? If unvaccinated people are really at high risk and know that vaccines are available... then who are YOU to tell them they cannot assume those risks?
The risks associated with alcohol are very significant. Close to 100,000 people will die EVERY YEAR from alcohol related causes. Do you propose roaming breathalyzers at football games or to prevent these "dangerous folks" from entering?
