Erm. definitely not. That statement is basically mixing up gender and sexuality to bring a whole new level of ignorance into the mix. so: gender is who you ARE, sexuality is who you’re attracted TO. that’s all there is to it.
so, a trans* person is trans* because their gender does not match the genital organs with which they were prescribed at birth. At least, this is the simplest way to look at it.
A gay person is someone who is attracted to someone who is the same gender as them.
so, got this? great let’s complicate it a bit more.
Therefore, Person A who is a female to male trans* (transman) is dating Person B, a cisgender male. They are a gay couple. Regardless of what their genitals are, they both identify as males and therefore this makes them a gay couple.
In short, sexuality and gender can be associated but they’re completely different concepts.
