Some nationalities are convicted of some crimes at a disproportionate rate. You cannot extrapolate they are more likely to commit the crime without looking at everything that happens up to that point. You first need to take into account the institutional racism of the police, and the inherent if not racism, then racial bias of society.
If a woman meets a guy in a bar, and she has a few drinks, then he assaults her on the way home, statistically, that crime has a very low chance of being reported. Will they believe her, will they be treated with kindness and compassion, what will her friends and family say?
Once she has reported it, she faces the judicial system, what is the likelihood the CPS bring a case, what will the court case be like, will they tear her to shreds, will the jury believe her?
When you put both of those sets of questions to a situation where it is standard white guy, or an asylum seeker/refugee/immigrant from a country which is deemed to be full of men who assault women, which one do you think is more likely to be reported for, and then convicted of the crime?
Study after study shows that black or brown men are far more likely to be convicted of a crime and the sentence will be longer, than white men in the same situation. This doesn’t mean they are more likely to commit the crimes.
But let’s, for the sake of argument, say you are correct and these men pose a higher than average risk to women. Even if we sent every single one of them out of the country, the affect it would have on the numbers of assaults that were committed would barely be a blip.
Reform, and the other groups of people who are making this about women are weaponising female violence for their own aims. They are doing nothing to prevent female violence and in fact, data shows a high proportion of those arrested at protests have domestic violence convictions.
You might not have a problem with refugees and immigrants being here other than this one issue. You might believe if none of them ever committed a crime, you’d be happy with them staying, you might not be racially motivated, but the people who are standing beside you are racist, they do want to see everyone sent out of the country, and some of those are very far to the right and have some even more extreme views on immigrants (well, the black and brown ones at least) Are you happy to walk along side them? If the answer is yes, you might want to ask yourself why.
