Leave aside the trans issue for the moment. The more I think about this More in Common think tank, the more annoyed I get.
If your aim as a think tank is to find out that people have more in common than not, then that is what you will find out. You can apply that methodology to anything: race, immigration, refugees, the EU, the monarchy, taxation, benefits, unemployment etc etc.
Because, how do you tell whether people have more in common? Is it numbers? eg if 50% of people think that sending asylum seekers to Rwanda is a good thing and 50% don't, what does that tell you? What if 90% want to send asylum seekers to Rwanda? What if only 20% do? I can't see that numbers tell you very much at all about polarisation/more-in-commonness, except that you'll never get 100% of people agreeing on an issue.
The big measure, surely, is how strongly people feel about something. Do you really really want to send/not send asylum seekers to Rwanda, or don't you much care either way?
Now in this trans survey they seem to have found that a lot of people weren't that bothered about the trans issue. Fine - they don't care enough about the issue to have polarised opinions. But all that really tells you is that most people aren't very well-informed about it, which therefore makes their answers unreliable. If people were aware that a trans woman might be someone who has had no surgery, no hormones and no GRC, might they still be quite so relaxed about letting them into women's spaces?
I'm not sure I've explained this very well but I hope people see what I'm getting at.
