You are correct.
England has a long colonial history, in which we have maintained this national identity of "civility" or being "civilised".
This has been used as both an excuse for our colonial violence (we must bring our ways to "uncivilised" people by colonising them), and reframed our violence as "protection" against fictitious threats (the violence is because of the threat "uncivilised" people post to us and our culture).
This, of course, relies on the othering of groups of people in order to justify English violence towards them.
You'll see some people on Mumsnet referring to themselves as "indigenous English". This is an attempt to completely invert the understanding of our colonial history, in which the English have largely been the aggressor and displacer of other cultures. But that's okay, right? Because we're "protecting" our British values.
Similarly, when England talks about "protecting" women and children, we are talking about continuing the men's role in maintaining hierarchies of oppression. These are the same dynamics through which women are oppressed. Men must "protect" women because we couldn't possibly be people with our own voice and agency.
If this was anything to do with the rights of women and children to live free from violence, women and children's voices would be centred. We know the threat to us is largely in the home, because we, our sisters, our mothers and friends have experienced it.
