I made no such definitive statement ie MUST I said TEND, that's been my personal observation based on friends aged 20's - 60's who are from certain cultures where such actions would be frowned upon.
The cultures my friends are from include Caribbean, Muslim, middle eastern, sub-Saharan Africa, south east Asia, South American, fundamentalist Christian, strong Catholic cultures (I was born and raised Catholic myself, well supposedly my parents kinda cherry picked the aspects they adhered to).
Both from knowing and speaking to my friends of Caribbean origin/background 2 of them their mothers were single mothers and the attitude towards single mothers was a large part of their motivation for leaving.
Several posters have noted it would not be surprising in a strongly religious household to hold such views and most religions in my and many others opinions are deeply patriarchal and misogynistic.
Also as posters have noted it tends to be a view more likely to be held by older people, but i don't think it a coincidence that previous generations also tend to be more likely to follow a religion.
In secular, arguably westernised (although I'd argue again that certain christian denominations can be equally misogynistic) cultures where the sexes are GENERALLY treated more equally as a whole this is less of an issue.
I've certainly got a few friends where the parents - predominantly the father - has been fine with a son having a girlfriend stay over in same room but has barred the daughter from doing so - in a few cases even though the daughters were older AND the boyfriends more long term "serious relationship" whereas the sons gf were fairly new at points where the sons were allowed to have them stay over in their room - blatant sexism.
Notice too throughout the thread it is mostly fathers that object.
It's at heart about men not in a romantic relationship with the adult female thinking they have the right to comment even CONTROL that adult woman's sexual activity, sexual expression and sexual relationships.
That's absolutely not on.
Some posters have asserted "his house his rules" but have also acknowledged that the daughter can vote with her feet.
Such a defensive even hostile attitude to a daughters partner is not going to lead to warm and fuzzy feelings between dad and dd it's likely to cause resentment and potentially a rift.
