If you think about it LGBTQ actually should be G
The L stands for Lesbian which is just gay for women
Bisexual means you look women but you also like men, and liking men is kinda gay if you ask me, T stands for Transgender and lets say if you're a transfem (Man --> Woman) Now that you're a woman if you're attracted to men that makes you gay because you are biologically a man, And if you're attracted to women, that means you're lesbian because you transitioned to a female, and lesbian, once again is just gay for Women. And Q stands for queer is basically also gay.
