First off, not everyone in the LGBT community support eachother…There are many lesbians and gays that don’t support Trans people either, because they might believe it attempts erase woman, or gay people’s sexuality, itself…But they are still part of the same community…They are still an alliance…
And why? Because of the idea of “intersectionality”…This is the concept that says, even if your community disagrees with another, as long as your are both considered marginalized, you are automatically allies against the “oppressors” of society…And because the Cis, white, Christian, male has been deemed the oppressor of society, according to the Left, it makes gays, lesbians, and Trans people automatically allies…
Now, based on that concept of “intersectionality, because Pedo’s (regardless of sexuality) are a marginalized community, too, I could see Pedo’s eventually added to the LGBT community…It only makes logical sense, based on the Left’s own ideology…😉
