Trans people are not a marginalised group in the UK.
They have created this group and self-identified into it, and identify as oppressed and marginalised despite having the same rights as anyone else, plus extra privileges which no one else has.
They obtained the right to marry someone of the same sex over a decade before gay people did.
They are the only people in the whole of society who are allowed to use single sex spaces for members of the opposite sex.
They have the more or less unquestioning support of Labour, the Lib Dems, the Greens, the SNP, Plaid Cymru and some of the Conservative Party, plus the Civil Service, the Police, the NHS, the BBC and the vast majority of celebrities.
They have powerful lobby groups such as Stonewall, as well as over 300 other LGBT+ charities fighting for their interests.
They can get people fired for tweeting that sex is immutable or that the "cotton ceiling" is homophobic.
They have created a culture of fear in many workplaces where other members of staff do not feel safe objecting to mixed sex toilets or being required to state their pronouns.
They managed to convince the NHS to remove sex based language from information about women's health, thus disadvantaging various other groups who need clear and unambiguous language.
They can show up to peaceful women's rights demonstrations with the sole aim of stopping women from being allowed to speak, behave violently, assault women, and the media will describe them as brave people fighting for their own rights in the face of mindless bigotry.
They can be convicted of rape and still be allowed to serve their prison sentences in women's prisons.
They have succeeded in getting their personal belief system taught to young and impressionable children in school and in educational literature as though it is fact.
They are allowed to dictate how we refer to them and also how we are supposed to refer to ourselves.
They have an entire month of the year plus numerous other random months and days dedicated to celebrating them.
How many other groups have this kind of political representation?
If most of the corporate world turns its logos rainbow coloured for the whole month of July, if Twitter and Facebook and Instagram are prompting everyone to declare their pronouns, if the governments of modern western democracies are passing legislation making it illegal for people to refer to your biological sex or to treat you the same as other members of your biological sex because this offends you, YOU ARE NOT A MARGINALISED GROUP.
