This is such an interesting and tricky area.
The stuff about people self censoring when with friends, family, work etc.
That's surely not new at all, at all unusual, and not a wow, really! Thing surely.
In our culture as well, certain topics are generally avoided in various contexts.
The well known 'never discuss politics or religion in polite company' thing Google tells me originated in a USA business etiquette guide from 1879.
Immigration, I mean. Not a topic to raise with anyone as v sensitive and even if roughly on same page, still likely to lead to disagreement/ arguing.
Politics/ anything to do with discrimination, minority groups, if you know you opinions are v definite and generally considered a bit extreme...
Would I start a conversation about patriarchal oppression, the continuing dominance of white privileged men especially older ones, just looking around it's obvious etc..
When with family including my dad- wealthy background, boarding school (from 7, implying that is privilege is... Well a topic in itself), medicine at Cambridge, pension bigger than my salary until I was about 45......?
Well no. I mean how would that go down?
(Those aren't my views much more nuanced which is another reason to avoid complex topics unless it right situation!).
I mean all the time we self censor.
Interestingly when it comes to people work fairly closely with, people I don't know that well, friends, family.... Blokey mates in pub...
When males in women's spaces comes up (and that's IME the main bit people are interested in), raised by others I don't as I know what I think.
It's been no disagreement, no arguments, total agreement. Each time.
So that's. Interesting...
