The co-founder of the Black Panthers, Huey Newton, saw gay rights, women's rights, labor rights and black rights as all inextricably connected. David Munroe, Ororo's father, was the son of Black Panthers.

As for Ororo's mother, N'Dare, it is impossible to speak on her culture's beliefs as her culture has never been adequately explored or defined. That said, as an ancient, primordial people going back the dawn of mankind, it is safe to say they were not Christian or Muslim, which is where the vast majority of homophobia in Africa originates from(also anti-colonialism, as there have been many instances of male Europeans in various factions raping young African boys, so some see homosexuality as a form of Western colonialism/oppression). That said, there are many instances of native African cultures that embraced homosexuality and various forms of transgenderism/gender roles/identity.

Storm is not Christian. She does not bow to any of its tenets. She is pagan, she worships a Goddess as manifest in nature. She is a nudist and in her original characterization, very distrustful of Western culture in general.
Her relationship with Yukio was a watershed in her development and it takes but the smallest leap to see her love for Yukio included a sexual component(fun fact, no Marvel comic character has ever been depicted with their genitals in or around another character's genitals/any other orifice, so
none of their sexual activities are strictly speaking canon).
Speaking of canon, for all these pages of exchange, I don't see much in the way of actual comic panels. Let's examine the evidence...
"...the tug on her heartstrings is too strong. The dream, too welcome." No one feels that way about 'their friend'.
Why would T'Challa, a very smart and self-assured man, have anxiety about Yukio offering Ororo her fruit, if there was no sexual component to their relationship?
As it stands, it's all subtext, as in the old Claremont run, same sex relations were explicitly forbidden, and more modern writers have only danced around the issue. But it really is crazy to see so called Storm fans, Storm a character who has always pushed social norms to the side in her very being not to mention her standing up for all oppressed peoples, spitting on the very possibility that Ororo loved a woman.
