Given that there are large amounts of genetic markers at play that determine how the body expresses gender, It makes perfect sense. I was trans-phobic until I found out one of my friends was transitioning about a decade ago and he explained to me what it was like living in a body that didn't feel like his own. If the hell he felt every moment of every day living in a female body is anything like the occasional skin-crawling torture I feel when my OCD is acting up, then my hat is off to him for surviving long enough to complete the transition.
The first image - the tweet - is a real piece of work. I worship at a very racially integrated church near the Gulf Coast. It's also a very poor church; we feel called to go there, but that's another conversation. A good portion of the church's black population voted for Trump this past election out of desperation. The Democrats offer opportunities to get out of their situation that never appear, just more rules and regulations to keep them locked in where they are and fat and happy while the people they voted for line their pockets with corporate money. They feel like the Republicans want to roll back as much of the dignity and help as they can and put them right back into Jim Crow. You can't pull yourself up by your bootstraps when you're not allowed to have bootstraps and Massah has his foot on your head (to quote one of the Church Mothers in my congregation).
Trump offered them dignity. He gave Southern whites a new enemy - LatinXs - that wasn't them, even if Trump can't figure out which country they're actually coming from.. He promised to bring the jobs to them so they wouldn't have to spend every last dime moving to jobs that never pan out. The jury is still out on the jobs (they're being created, just not here and not for them), but they have a temporary reprieve from the circles of hell they were stuck in with the two mainline parties.
If a black businessman drives around in a BMW with right-leaning bumper stickers, good for him. It's a shame that girl had nothing better to do than complain about someone exercising their liberty.
