Most feminist convictions, such as it's in women's best interest to get into 50/50 relationships. Until men are the ones to get pregnant, give birth, take care of children, do most or all housework, do most or all family admin - AND work on top of it all...women should not contribute a penny to bills.
Allowing 14 year olds to have "boyfriends", and treating them like they are the husband of their said 14 year old.
Normalising leaving shit stains in the toilet. And normalising poor toilet habits and hygiene in general.
Blended families. Most ridiculous thing that doesn't work. And it's unfair to the children that their space, parent's time and money get wasted on other people's children.
Letting children rule the household, being scared of your own children, being scared of "pushing children away" so you accept nonsense, age-inappropriate behaviour from them and generally taking on a super 'lax and undisciplined approach to child rearing. Parents aren't supposed to be their children's best friend, they're supposed to be their PARENTS.
Excusing bad behaviour, lack of social awareness, lack of manners and selfish, grabby behaviour with "autism".
Tolerating horrible men that are alcoholics, gamblers, porn-addicted, cheaters, liars, drug users, have no job, expect women to spend their money on them...the list goes on.
Moving men into your home after a few months of dating. Plus points if you have children and doing this shit. Shame on you.
Denying that biology dictates how men and women behave, and what things they gravitate towards.
Veganism.
Getting pets when you are already overwhelmed emotionally and financially.
Tolerating being taken advantage of, and allowing people to use you and take, take, take from you without ever getting anything back.
