Self-congratulation of the 'my DH would NEVER do that variety'
Man hating and double standards - I am thinking of a thread a few weeks ago when posters were saying it was perfectly OK to hide a pension from your husband.
Hyperbole - my DH told our daughter off - Is he always so abusive OP? My DH has a can of beer four times a week - I could not live with an alcoholic OP (see also self-congratulaton above)
The assumption that a baby is 'my baby' with the father playing a bit role as and when the mother allows it.
The constant drama about MILs feeding the baby, talking to the baby, looking at the baby
The narrative that not allowing anyone else to hold, feed or in any way interact with a baby is entirely normal behavior. It isn't. See also banning visitors.
Self-congratulation again, this time about voting preference. 'I vote for Labour because I care. You clearly don't'
The refusal to accept that, for most voters, the trans issue does not even come onto their radar when deciding how to vote
The shouting down if any criticism of the NHS whatsoever.
The whataboutery. A car blocked my drive - maybe there was a medical emergency? Someone walked past me when I fell - maybe they were rushing to pick up a sick child? A woman pushed me out if the way to pick up the last pint of milk - maybe it is the only thing their terminally-ill child can drink? All of the above might be true but it's much more likely they were just being arses. I always wonder if the OP would not be annoyed in the above circumstances in real life.
Teenagers - my teen won't tidy his room. 'That's ridiculous OP - even my two-year-old helps me with the tidying. I know this will never be an issue in this house because my child actually enjoys helping me' See self-congratulation above.
Picky eaters - my two-year-old will eat ANYTHING because hecqas introduced to a wide range of foods from the beginning. He point blank refuses to eat anything from a children's menu because we are superior parents'
The assumption that women know everything about parenting from the moment they give birth, yet their mums and in-laws, who have been through it at least once, know absolutely nothing, leading to the need to initially 'gently explain' where they are going wrong and ultimately go nc because giving food on a green plate just isn't acceptable now. It might have been when they were bringing up their children, but research moves on.
I think maybe I need to find another site!
