I think this thread started off in Chat (not Feminism Chat), which is where the original "What’s the most controversial opinion you hold?" thread is located but is full.
Then, due to the nature of the topic, Mumsnet shunted it to FWR 🙄
Unless the OP cunningly started a thread in AIBU in May to establish a false persona: they are an adult; originally from the UK; who normally lives in "North America"; but is currently living in the UK looking after their father and has a daughter in Canada.
Not clear if M or F.
So many weird contributions to FWR recently and Mumsnet Advanced Search being so effin useless that I am routinely using an internet search engine to search for, eg. "Manfreglory" site:mumsnet.com
Double quotes around the user name helps to exclude false positives from search results.
Some of the other unusual posts that have been plaguing us, that I wrongly suspected were made by new kids on the block coming here from Reddit, have turned out to be from long-standing Mumsnetters who are not FWR regulars.
Mumsnet's habit of shunting threads that started elsewhere into FWR is not helping things. Particularly when neither the OP nor FWR regulars realise what has happened.
It would avoid misunderstandings if MNHQ made an announcement in-thread when they did this.
