The notion of a 'LGBTQ community' is a recent invention created by sticking a T for transgender onto an existing LGB community. It is useful because it enables trans rights activists to appropriate the struggle of lesbian and gay people, and creates an illusion of a long history e.g. pushing the GRA15 through on the coattails of the Marriage Equality reference, the ahistorical claim that the Stonewall Riots in 1969 were started by transwomen, etc.
Transgender people and lesbian and gay people are two different social groups with different identities, different histories, different issues.
There is no logical reason to include a group of people who believe that transwomen are women/transmen are men with people who are sexually attracted to members of their own sex.
'LGBTQ' doesn't make sense.
How is asserting that some men are women 'safeguarding' women's rights?
By removing the social categories 'women as in biological women', specific women's rights as such disappear.
The GRA2015 created the legal fiction that some men are women, and that all they have to do to become women is to say so. The law is sometimes an ass, but that beats Banaher.
Hard-won Sex Equality legislation which protected the specific rights of women - and men, of course - were retrospectively re-interpreted, so 'sex' is replaced by 'gender', and gender means.... the kind of vague abstract stuff that the law doesn't usually get mixed up with, but it certainly no longer means biological sex.
Sex is no longer a protected category in Irish equality legislation.
In other words, women - and men - in Ireland have recently lost the specific rights that used to be guaranteed by law.
I don't see that as progress, and I don't see LGBTQ activists rallying to ensure that women's rights are restored in law.
