The vast, vast majority of violence is committed by men.
This is true across time, place and culture.
We have significant problems with male violence here in the UK.
Some cultures, while still patriarchal, are democratic and afford many more rights to women. The UK is one of these.
Some cultures afford very few rights to women; some are drenched in misogynist religious culture; some are deeply scarred by horrendous war and violence; there is significant overlap between these societies/cultures.
It is self-evident that bringing men from cultures in which women are seen as of significantly less worth than men + trauma from war and violence + religious and cultural disdain for UK culture including the roles of women in society is likely to result in violence against women and children, as well as violence generally.
At least in theory, the UK government has powers to prevent this additional threat to the safety of people already here in the UK.
It is neither sensible nor practical to say that we should not worry about preventing further male violence from immigrants until we have solved all our existing male violence. Nor
should victims of violence by immigrants be seen as collateral damage in the meantime. This argument is especially stupid when it is obviously a way of protecting the arguer’s political sensibilities.
