I wear an N95 daily and I get a lot of harassment. The lightest is random people on the street swearing at me, and the worst so far was a guy stalking me home to tell me my mask contained 49 heavy metals and cornering me. I am quite afraid for my physical safety at this point especially as also queer and self defense in this shithole is basically illegal. People constantly ask snarky side remarks about why I wear a mask, and it’s so tiring but at least I wish it was only that and I didn’t need to fear for my safety
I’m not sure if this would work with masks but whenever someone has tried to debate lord me over not eating animals I start viscerally describing the most horrible aspects of the meat industry I can think of and they generally back off immediately. Maybe get a little manic and start talking about how Covid will fuse your brain cells together and that you don’t want brain damage, if you can hold your eyes open extra wide while you begin ranting, almost like they’re not there they’ll probably leave you alone.
People have a tendency to become automatically confrontational when they perceive that you’re doing something they probably instinctively know is bad but aren’t willing to inconvenience themselves over.
