Titles that start Why do men..?
When it's not 'men'. It's the man you chose. Don't assume we all made the same shit choice!
Threads about FWBs which paint all men as sexually incontinent predators and presume all women are morally outraged defenders of sexual virtue who can't have sex without falling desperately in love and hoping for something more.
Dull threads about how often people do laundry/clean the bathroom.
"What's Mumsnet up to today?' Usually on a Sunday. Who actually cares?
Threads where someone has posted about becoming pregnant early in a new relationship with a man whose already shown themselves to be an abusive dick and need to process their decision on keeping it or terminating. The threads themselves don't bother me but all the, "I had a baby with someone lovely with a year of meeting them and we're still together 20 years later so you'll be fine too!" And, "But its a baby. And all babies are wonderful. And you should have babies!" type responses really irk me.
And all the ones where a woman posts about discovering her partner is cheating during her third pregnancy and doesn't know what to do when it transpires that she caught him cheating at the start of the relationship and messaging sex workers before she became pregnant with the first. Believed his remorse and conceived a second child in celebration and has realised by the third that he isn't going to change. Again, it's not the women/threads that irk me though. More the societal expectations and pressues that mean many women will hang into a relationship for dear life rather than think, "Fuck that, I'd rather be single!"
