Hedgehogs get squashed and birds get hit by vehicles because they have not evolved fast enough to learn to avoid them. Over time the ones who have survived will pass on something that allow more and more to be aware of the environment they now live in.
I think much the same is happening with new ideas and concepts in society. Sexuality and gender, the new research findings and biological basis for such 'phenomena', shall we say, together with new acceptance and legal entitlements are slowly finding their ways into a woder, opem mindset of society at large. Such evolution takes time BUT it is rapidly developing and less random than evolution in the bigger sense.
I am not against folk who have problems understanding new concepts and ideas. Like learning a new song, some need crib sheets and pick it up slower than another would, but in the end the song is learned hopefully and plays a part in wider music scene as it spreads.
I don't understand nor like football. Last night I hated rugby because, after turning up at 7pm for a gig, only to not be able to set up in front of the big screen behind the stage, I had to wait until 9.45 to do it all and hasty sound checks, after the rugby had finished. I respect that others like football and rugby and that is not their fault just because I do not like it. We all still got on well and a good gig was had by all once started.
Acceptance causes far less anxiety for all than enforced tolerance. Times they are a changing ;) lol
