I'm going to explain this very slowly for you to understand again.
Who names these groups?
Is it women's rights activists or is this the media and political leaders?
Are the two groups the same?
What happens if there is a social problem that is not being noticed by the media and political leaders?
Women's rights groups are noticing something cultural that is negatively affecting women. This needs to be discussed without emotion. This is hard to do without being accused of racism, but if it is having an adverse affect on a protected group under the Equality Act it is worthy of discussion. The point of the Equality Act is to balance interests and prevent harms to a group.
If one group is asserting power over another group to their detriment this is where the media and political groups should step in to address the issue in a responsible manner. This isn't what we see happening so you get ideological opportunism to capitalise on the issue.
The women's rights groups are centred and focused on the impact on women. If there is excessive cultural prejudices to women which are being imported with high levels of immigration from a particular community it is relevant for women's groups to discuss these harms. This does NOT make them racist (though it can be hard to get the tone absoluetely spot on at all times).
The problem overall with rights and equality in the UK at the moment is that it has forgotten this concept of balancing needs to prevent harms and the idea that it can be quite complex. A white affluent woman can be more priviledged than a male immigrant, however a male immigrant can be more priviledged than a female immigrant. Also, large numbers of male immigrants can hold power over a single white affluent woman in certain situations. So it is important to discuss these ideas on a case by case with it in mind that it can be completely dependent on the situation.
What identity politics does is impose a rigid hierachical framework which does not allow for this nuance. This creates a problem as it is not sophicasted enough in thinking to prevent harms in certain situations. The media and political groups in supporting this concept rather than the Equality Act's principles in law, creates a situation where the this lack of understanding of rights and how the law should work and it allows abusers to evade the law and allows Far Right can capitalise on it.
One of the most disappointing things in all of this for women's rights activitists of many years standing, is that that can see this and the current leader of the opposite was a Human Rights lawyer whom for this should be his bread and butter, yet he's fucked it in the head.
So please go away and think about what womens rights groups are doing. They are trying to protect themselves with the law and to balance their rights in the correct and appropriate way - like they always have. They are trying to asset the rights and protections they should have rather than degenerate another group.
