The Overton Window moves. It narrows and widens. That isn't the same as being unable to be yourself.
I agree that men should be socially allowed to have spaces where women are excluded and society does sort of tend to look down on that kind of thing, but I also think that in a world where many professional environments are still male dominated some sensitivity to the exclusion of women is warranted.
I mean plenty of jobs out there are still 95% or more occupied by men only.
In term of total gender segreation in the work force, about 15% of men and women work in gender equal profession. The majority, both men and women, work in a job where their gender outnumber the other gender by 2 to 1 or more.
A common finding in studies conduced on this statistics is that gender segregation occurs also within a profession. Teachers is used as the typical example where gender segregation occur on both subject but also on level. It also get worse as people advance in their careers, with each "step" on the ladder being a point where the minority gender decrease.
I see what you mean. To clarify: I meant as a group, rather than as individuals. I appreciate there are smaller-groups that also can't be themselves somehow, but if that's a sin, then perhaps the larger group not being able to be itself is a larger sin.
Imagine how this comment would come across if applied along any other demographic axis.
I'm not sure that's quite true. Men tend to talk and joke in a different way to women, which they then modify around women or be punished. The main difference between an old-school Personnel department and a modern HR department is HR is (self-)tasked with making sure the environment is always suitable for women.
Men have very few places, if any, where they can just be themselves, unmodified. And when those places exist, large shaming campaigns and marketing appear to tell them off and to entice women into them.
