Ive just returned from 2 weeks in LA / Disneyland. The mask wearing didnt bother me at all, in fact I double mask and wore them continually all day every day, even when technically not required such as outside. I put them on as I left my hotel room every day and only took them off when I was actually eating and drinking. Sometimes like when I had coffee I put them back on between sips. I used Photopass at Disneyland and kept my masks on for all photos, as I wear Disney Bounding outfits and the masks were coordinated and part of my outfits.
I found it was other people who had issues with me wearing masks. All the photopass photographers asked me was I sure I wanted to keep the masks on. The same at the airport when I was drinking Starbucks while waiting at my gate area and put the mask on between sips. A woman opposite me commented on how silly it was and didnt it annoy me. Actually I was doing it automatically and didnt even realise that I was doing it.
I think when someone like me, who double masks and wears masks out of choice , not just because the Government tells you too, makes people uncomfortable as many in America see masks as a political issue and an infringement of their rights and feel threatened when someone has different views to them.
And yes I did get stared at when I wore masks when the majority of people were not.
