First of all, you're absolutely welcome to post here as an ally.

Secondly, I found an informative article on thr queer news website them which explained everything:

The order, titled "Defending Women From Gender Ideology Extremism and Restoring Biological Truth to the Federal Government,” was one of more than 200 executive actions Trump issued on the first day of his second term, [...] disbanding federal programs on diversity, equity, and inclusion. [...] the document seeks to redefine gender at the federal level, erase recognition of trans people in government communications, cease the issuance of gender-corrected U.S. passports, bar incarcerated trans women from being housed in women’s prisons, deny gender-affirming medical care to trans inmates, embolden transphobia in the workplace, and block federal dollars from being used to “promote gender ideology.”

I live in the UK, so I only know what I'm being told, but the situation looks pretty dire over there.
