It's not why I've posted it, as I said in my post that you've quoted. All I've tried to do with it is to deflect the accusation that feminists are 'just like right wing religious people' (or some other group that they try to compare us to through a misinterpretation of our concerns about trans ideology).
But if the description is kind of fudging the difference, than does it really show that?
I mean, to me, the statement that they are the same is just clearly wrong, and probably not honest, at least from someone over 20. Anyone can see that the two groups differ significantly on a number of issues, and there is no need to unpack the origins of those differences to show it.
As far as it goes, it's try that radfems and religious conservatives generally both see the body as real, and that accounts for a lot of their overlap on this. There are probably some other similarities around thinking about class groupings as well, as opposued to a liberal/individualist perspective.
But I don't think that characterisation of the difference, which you want to show, is something many conservatives would recognise, and presumably the people who are looking at the diagram could be aware of that. So it doesn't especially show them that there is a difference, that is what is most likely to be in dispute. The response could easily be "That's not really a conservative position, so what is this difference you are saying this shows?
