Your vaxleth post is so bad. Yes bisexuals dont become "straight" at any moment but saying "heterosexual relationship" at no point in the real world means "both people are necessarely het" it literally just means "a man and a woman in a relationship". Also the "-sexual" has never been exclusively about sexual attraction (thats a mogai fabrication, as the sam cant be expanded to non-ace people) it has always been about the genders one is attracted to. Also one can be both ace and het too.
The fact that you think that this is about shipping demonstrates that you pretty much missed the point from the beginning.
In the “real world” there’s a prevalent perception of bisexuality as “fake”, as a phase, that bisexual people are selfish, or that they just can’t make up their mind, or they just need to find the right person. This is a perception that exists both among people outside of the queer community and inside of the queer community. Those perceptions don’t come from nowhere, and mislabeling the relationships bisexual people are in as “het” when they’re with a person of a different gender perpetuates those ideas.
Some argument of “but this is what these words are accepted to mean” doesn’t actually contradict this discussion because that’s the whole point. There’s a popular and accepted usage of these words within our community and society, and that popular and accepted usage is inaccurate, harmful, and erases bisexual experiences in ways that lead to exclusion and discrimination.
And yes, the suffix of “-sexual” is exclusively about sexual attraction, speaking both in a more clinical sense and in the more modern language within the queer community. That’s why we have terms that separate the way someone experiences sexual attraction and the way someone experiences romantic attraction. A person cannot be asexual and heterosexual. They can be asexual and heteromantic. A person cannot be bisexual and homosexual. They can be bisexual and homoromantic. And yes, the “-sexual” suffix being used to describe how people experience sexual attraction can and does apply to asexuals, as “asexuality” is a term that describes the fact that we don’t experience sexual attraction.
