When I was in Scouts, there was not a SINGLE woman in the room at our meetings - it was "man hour", no girls allowed. Cub Scouts is where women should still largely involved, Webelos to a lesser extent still. But Boy Scouts ought to be an exclusively man thing, as far as meetings and events go. I don't blame this lady for changing troops with her son.
Back in the early 60’s I finally reached the age where I could attend 2 weeks of summer Boy Scout camp with my older brothers. We billeted in wall tents that had a wooden platform floor and cots. My mother started to make up my bed with sheets etc.
The Scout Master saw what she was up to and politely threw her out before she could get started...
The only time my mother went to ANY meeting was when my 2 brothers got their Eagle Scout badge.
