How do you explain then the far more appalling way in which women and children are treated in many of the countries these men are coming from, if culture is not relevant?
Many of them have no laws against marital rape, or beating your wife and children, or sexually abusing children, or “marrying” and raping children, or treating women effectively as slaves and imprisoning them in the house unable to go out without a man, “selling” children as slaves/ abuse victims, they do nothing about gang rapes of women which are commonplace and even punish women for being raped if they report it.
And you think that their culture has no impact on their values and behaviour?
The men coming here from such places have been raised with these cultural “values”. They aren’t going to have an epiphany because they are given a leaflet. Do you think none of them participated in the horrific crimes above, which the societies they were raised in consider to be the norm?
