> a union should be monomanically about representing worker interests and stay far away from any other kind of issue

So...should it pick and choose which kinds of workers to represent the interests of?

Or should it fight for the interests of all the workers?

Because that's really the choice it has to make: do you fight for the interests of disabled workers, and female workers, and trans workers, and black workers, and immigrant workers? Or do you only fight for the interests of white male workers?

Either choice is a political choice.

You cannot avoid politics when one side of the political aisle has declared that the validity and ability to exist in public life of certain categories of people is against their agenda.
