Probably unpopular opinion here. First, it's the person's right to wear whatever mask they want. Complain to the company if you want. I emailed them.

Second, I personally find wearing the flag mask offensive and refuse to do it. People are literally wearing the most recognizable symbol of our liberty in celebration while liberties are being taken away. I have TWO flag masks. I don't wear them anymore. When the government forces behavior like this, forces you to cover your face, your rights are being eroded. Nope. Not wearing the flag for that one.

Someone got me a pair of flag socks. I said thank you. Then refused to wear them as I never felt right walking on the flag. Flag boxers are the same.
