This. If you don’t like it, fly another airline. But, of course, if you don’t stand up for your rights to be maskless, they’ll soon require you to wear a tutu or... something.
The way to stand up for your rights is to deprive the company whose policies you disagree with of your money and complain to the corporate HQ while not using their services. Throwing a toddler’s temper tantrum and ruining everyone else’s day when they didn’t have anything else to do with it is not the way to do it.
Having “rights” is between you and the government. Once you step on that airplane, you loose your rights. However you do have the right to fly a different airline.
