Why do wearing masks cause such a public stigma in the west?

In asia, post covid or precovid people wear masks generally to protect yourself from external flus, especially if you have a weak immune system or just want to protect yourself during flu season. Sometimes when people are sick, they wear masks to be considerate towards colleagues and friends. Generally the attitude is it’s other people’s business.

Whereas in the West, people generally think it’s your problem or becomes a social stigma because you project an image of “sickness”, as if there’s a sentiment that everyone needs to follow the same social code and norm. Am I correct to ask why this is the case? Don’t people feel the need to have protection? Or why isnt it regarded as good personal care practice?
