You pass enough that I feel like the majority of people would assume you're a woman. I feel as though anything than could have clocked you is also prevalent in multiple cis women. Might just be some trans paranoia bs.

I feel like passing as trans and passing as cis are two different things, and while I personally think you pass as cis, I guess you could be riding the line between the two for others. Additionally I feel like it could be an instance of luck or area as to why you got misgendered. I personally am earlier in my transition and am much further from passing than you are, and haven't gotten misgendered in forever.

There are a lot of stupid out there, but l promise you, you pass a LOT more than you think you do! :)
