One of the aspects of the more vocal transgender orgs and activists allies etc that makes me so angry is their shameless theft and repurposing of theories, arguments, even slogans of loads of rights movements. Often directing them back at the groups who came up with them, often destroying the concepts in the process.
Relating to your post-
The very useful very important concept of intersectionality.
That was an accessible, considered, important set of arguments.
That most people are poor at thinking of things that are outside their experience, their personal situation. Things not personal are just out of mind.
That there are loads of axes of oppression. And focusing on whatever is most important to you is aok obviously.
That the more characteristics a person has that are of a group oppressed, the more shit they get. The barriers from each add up, making overcoming them increasingly hard/ effectively impossible.
Important and not difficult to understand the headline point.
Taken, bastardised into oppression Olympics, used all the time in an accusatory way to individuals/ 'types'grouped with names that irl just got backs up.
Result.
Intersectionality derided, original concept steamrolled over.
Used to provoke division, anger, to insult and dismiss certain views / people. And (dangerous) to feed resentment in groups who, if they kick back, are in the position to really make it hurt.
Rather than increasing understanding, remembering to consider those who aren't same boat as you, reduce disagreements etc.
That's one example of many, I thought of it when read your post.
