does "girls and the gays" include lesbian cus gay is an umbrella term or...

like sorry but this is srs. I mostly see "girls and the gays" referring to straight girls and mlm men, but like guys. Are other sexualities included? Mostly gay is used for a man who likes men but its also an umbrella term so like.. if lesbians ARE included, are they the "girls" or the "gays" part? cus not many people refer to lesbians as gay anymore and sometimes lesbians arent girls so this is a genuine concern I have pls send feedback
