What is a posters intention? If it makes a valid point of substance, it has value.
In terms of rudeness, given that some will consider asking questions about being aligned with the far right incredibly rude.
The OP demonstrates a fundamental lack of knowledge of the history and development of gender critical thought in the UK.
In the UK it has very firmly lead by women on the left who have been treated appallingly by the political parties they were aligned with or even belonged to.
We do not live in the US. We should be reflecting on why US politics is dominating the subject and allowing the crushing of the voices of women on the left in the UK. This is not ok.
Our laws are different to the US. We should debate this on the basis of our own law and our own legal protections.
For example if we replace the word sex with gender in law we literally erase the protection of same sex based rights. And this is particularly problematic for homosexuals because they rely on this for same sex protections. This matters. It's a removal of rights which is very much at odds with the values and principles of the left.
So why are people on the left suggesting that people we who have concerns about this are 'far right'. Is it because they don't like people on the left pointing out their hypocrisy and betrayal of those these leftists claim to support.
Replacing sex with gender is a betrayal. It is not an act of the liberal left. It is an act of authoritarianism. Authoritarianism is of the left and of the right and it never ever serves the people. It always serves the establishment and centres of power. It removes power from grassroots. And it is grassroots women on the left that have seen, experienced and been the victim of this most.
