Yes I have... Masks for me are just not an option most of the time. As a COVID scientist I did need to wear one in the lab (and i was of course not objecting), but it severely limited my lab time due to discomfort. Naturally as a result I never wore one outside the lab.
As a result if there was a particularly high risk area (like a nursing home) I'd just avoid the space rather than wear a mask.
Yes people have been violently aggressive about my no-mask stance even when I specifically made it a point to avoid high risk settings and generally avoided places a mask was required like any store that had a sign.
