BTW, I have personal connections with transgender people. They are old-fashioned transexuals who, while presenting as "women", know they are still male and don't claim to be women just like other women. In the transactivist community these people are sometimes called truscum.
So these people "know they are still male", so they have a male gender identity but present as women? Sounds more like your friends are cross dressers. Which is also fine, but wouldn't make them transgender necessarily.
And I looked up "truscum" and it looks like that term would refer to a transgender person who believes it is necessary to have dysphoria and medically transition to be trans. So a transperson who thinks non-binary people aren't trans would be truscum.
