Reclaiming a word is a great goal, but it starts in targeted local communities and then having those communities reach out to reclaim it in larger ones and so on. And it's much more difficult when both the intricacies of the literal meaning dont support the one you want and it's in active use to mean something different by people who don't believe they are using it in a bigoted way. It's much easier when it's very explicit that people are using the word as an attack like gay, bitch, the n word, etc., all of witch are in various stages of being reclaimed.
But if it's about communication and in a larger community like the internet or even a city of people, and there are more specific words that explicitly give those meanings rather than intricate socially defined implications, then it's better to use those words outside of the community you're reclaiming the word in.
In this case, if a cis-woman I'm interested in says they are bi, I will assume they are not interested in me vs if they say pan- or omni-sexual or use a word that has no explicit intricacies associated with it's literal meaning like queer. And asking clarifying questions might out me in a potentially life-threatening way. If a trans-woman I'm interested in says bi, I'm likely to be more inquisitive to figure out what they mean just like if they said queer. But again, that's a different community of people. Very few trans people are going to be bigoted against other trans people. But lots of cis people are bigoted in the current state of the world.
So feel free to try to reclaim it. I think that's a noble goal. I'm just saying that you may be misinterpreted in a larger community like on the internet or even localized dating sites.
