It's colonisation again.
During colonization, colonizers usually imposed their language onto the peoples they colonized, forbidding natives to speak their mother tongues. ... In response to the systematic imposition of colonial languages, some postcolonial writers and activists advocate a complete return to the use of indigenous languages."

Those of us who were brought up in British colonies are well aware of the way the suppression of the native language(s) is used as a tool to subjugate the population.
We see it in the gender wars all over the place. We are no longer allowed to use our language but must bow instead to our colonisers who define reality in a way that benefits them and them alone.
In universities where de-colonising the curriculum is very trendy, this argument goes down like a lead balloon with the blue haired brigade. They cannot claim their language is the oppressed one because terms like "cis", "transphobic" and "pansexual" are new to the lexicon of the native population. 
I thought about this when I first heard an American trans activist argue that the TERFS are ruling the Land of Women and keeping out the refugees they dislike just like Trump is keeping out the asylum seekers from the US he dislikes.
That was a light bulb moment for me. I realized that the tone of the trans activists is much more that of an invading coloniser.
So we, the original denizens of the Land, are now told that the basis on which one gets citizenship is not having a female body (the old law) but something else. Most history can no longer be taught because it is not inclusive of the colonisers, and this rules out any public discussions about issues having to do with the female body. Language is altered so that it becomes almost impossible to have clarity on anything.
In particular 'identifies as' replaces all other bases for claiming that one is a citizenof the Land of Women so that none of the changes the colonisers institutes can possibly infringe on women's rights because they identify as women and their rights are not infringed.
This is how transgender women are not a threat to women's rights anywhere, from elite sports to single-sex spaces.
When I first thought these thoughts I felt incredibly guilty, because I also have great empathy with people who suffer and who are harassed or treated terribly. But the more I read about these issues, the less guilt I feel. If the trans women were true refugees they would have silently merged into the general population and they would have waited until they have much more experience about the way the country works before they begin to alter all laws on us.
Refugees do not try to ban everything about the history of the country which receives them and refugees do not re-define all women's language for us.
