I've given it all some thought over the course of the day, and have no answers and am none the wiser. But I can't think of a less exclusionary activity than bushcraft given that for many people I suspect it involves; watching YouTube, solitary trips to the woods, reading and studying plant and tree ID, watching YouTube some more, window shopping on the internet, and spending a bit of time on forums where people are largely anonymous.
So I guess any issues are far broader, such as physical access to countryside. Perhaps trends, habits and fashions play a part too. I just don't know. But if the worst were true and we were a bunch of exclusionary types, then why wouldn't there be alternative groups out there, such as mostly female bushcraft communities, or other minorities etc?
Compared to other activities and areas of life I've been involved in, the bushcraft community, particularly on this forum, seems very chilled out and welcoming.
