SofiN, I've learned that it doesn't matter what they're thinking, it only matters how they treat you. Currently I work at a Walmart. You would think that Walmart would be the last place to get acceptance, particularly if you know that I walked in there so cautiously. I put male on my forms, dressed androgynously and did my job. We have poorly educated people, Hispanics with poor language skills and attitudes from small countries not known for accepting us, and "holy rollers". A few weeks of correcting people who misgendered me and I was soon accepted as one of the girls, by EVERYONE! I have lots of girlfriends there and people of all those types stop me to talk and treat me warmly as one of their own. I'm no beauty, as my picture attests (that's about the best I've EVER looked) and it doesn't matter. Do I still get misgendered occasionally? Yes, almost every woman does.
Yesterday I was looking for something in the shampoo aisle. A woman near me said, " excuse me, sir, can I get at the shelf behind you?" I stepped aside, smiling and saying "I'm not a 'sir'", something I used to be afraid to say to a customer. She replied, "sorry, GUY." "I'm not a 'guy', either." She looked at me and started gushing apologies, she said she was always doing that. Another woman in the aisle started giggling. We parted on a pleasant, happy note once I got her to stop apologizing.
Sometimes we're not really clocked. Sometimes the other person just isn't really paying attention and makes a wrong assumption. If we stand up for our womanhood (or manhood for our brothers reading this) in a nice way, most people will accept us for who we are. Confidence is Queen!
