@Melinda255 Airbnb is an international platform, so your America-centric viewpoint is irrelevant.
You have a choice whether to be vaccinated or not. When adults make choices, no matter what those choices concern, they are normally aware that choices have consequences otherwise people wouldn't weigh the pros and cons of things when making decisions.
You have no "right" to stay in anyone's home, enter a private business or a hotel if they require vaccinations, anymore than you have a right to enter barefoot and shirtless if that is prohibited.
Why on earth would you think that businesses which only accept vaccinated customers would care about your opinion on this?
And your anti-vax rant and misinformation has no place on an Airbnb forum. Save it for your anti-vax, conspiracy forums.
