I'm not against anyone jamming a spear in the ground and saying 'this is who I am'. I've jammed a spear in the ground and said 'who i am doesn't matter, listen to what I have to say'. I have no problem with identity or individual differences, I have a problem with dividing political interests along arbitrary lines and attempting to force the power for change in a selection of smaller and smaller niche interest groups.

I'm not sure what you mean by feminine discomfort? Do you mean females don't like it? Or that bisexuality is seen as a feminine thing so Conservatives don't like it? Either way, I don't see it as an LGBTQ+ issue per se, I also wouldn't like to see it leveraged as a feminist issue via the backdoor. My answer to the political attack ad (by the numbers) is that it would be illegal under protected characteristics legislations and not appropriate as an advert - we have a legal framework to deal with it.

I wouldn't mandate that people have to be comfortable with bisexuality (though i hope they are) I would simply withhold the scope to seize the apparatus of power to legislate against it. Pluralist societies are not harmonious utopias - they simply have to be tolerable for all involved. Prejudice will exist whatever you do. You balance it, you can't eradicate - and you certainly can't do it by groups of likeminded similar people joining together. That's anathema to eradicating prejudice.
