Its okay.

Well first nonbinary doesn't mean EXCLUSIVELY non male or female. Just you don't entirely identify as one or the other. For example, bigender people who identify as 50/50 male and female are considered Non-binary because they don't feel like they're 100% of either gender. If that makes any sense.
With the term transfeminine it means siding more with feminine features. So this person who's both transfeminine and nonbinary is someone who was assigned male as birth, identifies as some form of non-binary, and prefers to have feminine features.
Queer is sort of an umbrella term, usually by those who don't feel they fit into certain LGBT labels like gay, trans, bisexual, asexual, etc.

Thanks for the help with my questions, Wade :)

Ron White once said of being gay something that I believe you could apply to anything: That it's not a question of whether or not, but to what extent.

Ergo, it is possible to be two things at once, and the individual in question would probably describe themselves as "somewhere in between" T-F and N-B, or possibly "Non-binary with a feminine lean".

Thanks for helping with my curious questions, Terastas :)
There is soooooo much I'm still trying to understand. I can get confused about it at times.
