That is really dangerous thinking. It's not only a badge at all. And deciding peoples thoughts because they won't go along with what someone else has decided they have to support is seriously bad.
As I said, that's only one element of my thoughts on the matter, which are contradictory. And as I also said, I was wondering about people's motives, not reaching any conclusions, but I shall continue to wonder about the reasons people might have for wearing or not wearing a badge to commemorate diversity and what (if anything) that tells us about the national mood..
Do you think that their motives are any of your business? As long as they keep them to themselves?
Any event that makes the national news and that may (perhaps, arguably) be a measure of the times in which we live is my business. When it concerns an organisation I've been a member of for decades, especially so. It's not about individual volunteers.
