Why is it okay to be trans-gendered (i.e., Laverne Cox), but not okay to be trans-race (i.e., Rachel Dolezal)? Serious answers only plz.?

Because being transgender is a real thing, whereas trans-racial is not.

This guy it explains it well:

And gender is not a "mindset", gender identity is programmed into the brain during fetal development. I suggest you watch this new documentary: Katie Couric National Geographic show on transgender (rewind to beginning):

.

Race is defined almost entirely by who your parents were and how you were raised. Race is obvious in the physical characteristics of a person.

Gender is entirely internal. There are 0 external markers of true gender. When people assume gender from an unrelated characteristic (genitalia) then of course it makes mistakes.

The reason is things, like this.

You don't have a physiological part of your brain that identifies you to a specific race, or to another species. Transgender people, do, at with their gender identity.

I do not know where you got your information from but in my part of the real world it is most certainly NOT ok to be trans -gendered. These freaks are the most disgusting of nancy boy pooftas and need to be put down.

So long as you consider everything that happens in the womb prior to birth to be "biological", and how could you not, than being a transgender person IS biological.
