For the third year in a row Stonewall have helped stiffen the resolve of all those fighting the marginalisation and invisibility of bisexuality with a fine report on the problems and discrimination facing LGB people which makes all its recommendations in terms of what needs to change for 'lesbians and gay men' not to expect to face discrimination in their day-to-day lives. Political parties need to appoint lesbians and gay men to positions of high profile, and so forth.
They did the same thing last year on their social attitudes survey, and the year before in their LG(B) in the media report. It has been pointed out to them in many ways; on panels at public LGBT events; by postcard lobbying; in person to staff members. Alas, they remain resolute in their determination to pretend that everyone is gay or straight with none of the diversity of life in the real world.
This survey was conducted as an interview of 1,600+ people and so - given there are more bis than lesbians and gay men put together - there have to have been a fair number of bisexuals unless the sampling methods were so ropey that Stonewall should be demanding their money back from pollsters YouGov.
That could reveal all kinds of interesting things. There might be interesting gender differences in experiences and expectations. There might be evidence that 'bisexual privelidge' does have some statistical impact. It might show no statistical difference between bi and gay people, which would dispel the 'bi privelige' line. Or it might, like MIND's report into LGB mental health, show the impact that receiving prejudice from both sides has on bisexuals.
Alas, Stonewall's research team and statisticians haven't cared to explore any of that.
