Perhaps a bit too broad of an assumption about mask wearing.
I‘ve many friends who have been visiting WDW since it reopened and most continue to wear a mask (because the pandemic is not over). It has zero to do with their individual political beliefs, but rather because they feel safer wearing a mask.
It is the same where I live (red southern state)…mask mandates are a thing of the past for now, but about 30% of people still wear a mask inside stores and restaurants. I respect whatever each person decides is right for them.
