Like one trans woman I used to play video games with told me she wanted breasts, vocal cord surgery, BUT didn't want to change her other genitals. In her words "[my penis] is one of the few parts of my body I'm comfortable with"! Before I talked to her, i always assumed trans wanted to obtain ALL changes associated with their desired gender!
If you don't even care enough to read the basics, why should they think that you care enough to really understand them?
And there are writings from untold thousands of trans people, with different views, so it's not like reading will only give you generalizations. You'll get thousands of specifics.
From the Miles Davis album A Tribute to Jack Johnson:
> "I'm Jack Johnson, heavyweight champion of the world. I'm black. They never let me forget it. I'm black all right. I'll never let them forget it."
Otherwise you're the stereotype of an English speaker going to a foreign country and insisting that people can understand you if you JUST TALK LOUDER.
You don't even seem to be doing the equivalent of picking up a tourist book containing a few phrases to say.
Instead, read one of the many, many articles on this topic. Written by trans people or trans-friendly people who specifically do want to educate strangers.
