Drag Queens, the ones dressed up and wearing heavy makeup and parading, are performance based. They are designed to shock and draw attention and most are men who wear extravagant costumes. SOME are trans, but they do not base their everyday appearance off of their stage performance.
Drag queens have also been around for decades longer than even I have been alive.
Transgender people, either way, are not automatically drag queens and MOST are everyday people you work with, who pass you on the street and just plain want to stop being attacked or spat on for outwardly identifying as they feel.
I don't feel insulted put upon at all around my trans female friends, like Charlie who wrote these words. She's extravagant and loud sometimes and gods, get her drunk and she'll start singing...but that goes for a lot of people.
Maybe treat trans people like people and understand what performance drag actually is and then understand your outrage is misplaced.
