What i think of it? Hilarious tbh. But, considering how wild LGBTQ+ is becoming, shit, might do some good. Bs can get and organize their own group. Also, yes, they're probably serious. It's either "drop it" or change the definition of bisexuality to include their gender identity.

As for B being dropped from LGB or LGBTQ+, if there wasn't such a shitstorm going on, I would say drop and all the groups go through separate ways. We're not the same thing. Why do straight people get their own community but we have to be grouped together? It just causes problems.

Do you believe they are secretly gender skeptics(like us)?

There is no "us" in this. I'm just here because of the LGB vs TRA shit.
