I don't think the word "ordinary" helps in this context. What is "ordinary" is highly subjective.
Perhaps we could instead frame this as what is "generally socially acceptable." For example:
It is generally socially acceptable to think it is a good thing to be kind to and look after the needs of elderly and disabled people.
It is generally not considered socially acceptable to allow elderly or disabled people to be denied medical treatment if they become ill.
However, there are all sorts of values, moral issues and behaviours that fall somewhere in between. Even where they are not views held by the majority of people, if a significant minority hold them, they may still be tolerated by others - so are "generally socially acceptable."
So, although not eating meat is something practised by a minority of people, it is generally socially acceptable to be a non-meat eater.
Similarly, although seeing victims of rape as somehow responsible for their assaults may be a view held by a minority of people (say 1 in 4 from some of the research cited above,) it is generally socially acceptable to hold that view.
If that wasn't the case, you wouldn't have pro-rape sites protected on Facebook, you would see people who wear pro-rape tee shirts or make jokes about rape being roundly challenged for their choices and you would see mass boycotts of tabloid papers that print articles suggesting that women "asked for it," or otherwise were to blame for their attacks.
But, you don't get that!
