Since you mentioned Britain, I think you may mean me. I'd say that I didn't mock him in anyway. Nor did I dismiss his post.
Instead I tried to reassure him, as to me I think he's met some nasty people, who have tried to scare him.
He's already reported it to the authorities, what more can he do? Here in the UK such a report would not be disregarded. It would be recorded and assessed. Given the serious nature it would almost certainly be investigated.
The murder rate in the UK is typically very low. You are far more likely to die in a car accident than from being murdered.
The statistics I mentioned were mentioned by me with no intention of making any connection to you at all. I had completely and absolutely forgotten that you live in that part of the world when I shared that information. I mentioned this information because it is readily available, good quality statistics that I came across about killings of women in intimate relationships, in a very wealthy and well educated OECD nation. My remarks about listening on the forum were general remarks.
Over 70 women killed by men in intimate relationships in Britain is not a number that I can consider to be very low. If it is low by comparison to other mortality statistics, that is no meaningful measure for assessing its significance. It is shocking and deplorable that women are killed like this in a country that is so economically developed. I presented this simple and limited information as a context for the good possibility that other even more excessively violent crimes are taking place on women in the world.
You may think that he's met some nasty people who have scared him. Maybe that's true, or maybe it's not. You didn't present any detailed ideas about why you think it's unlikely that this kind of thing happens in the world, though, you just did not give the benefit of the doubt about the possibility that it does. Wouldn't it be more constructive somehow to discuss about our ability to assess available evidence about what is possible? I think it's difficult to have an open discussion in an environment defined and limited by assumptions.
Women are traded as though they are commodities in significant numbers for sexual slavery. All the time. Not even across borders. Women who have citizenship in the country where they are traded are being treated like this. It's commonplace for women to be traded as sex slaves.
There are certainly many other things that people can do apart from reporting things to authorities. I think that you will find that this is the story of social change in history, that change has largely originated from people who lobbied for change and pushed authorities to make it happen rather than because authorities decided it was time for change and benignly legislated change. It can come from anywhere, it can come from people organising on the streets, or in an internet forum. No one can make anyone else organise as part of activism about social change if they don't want to do it. There's no shame in not being an activist, many of us have very full lives and have no wish to participate in this kind of agitation. I live with a parent with multiple complex formal psychiatric diagnoses, I don't think I really have the energy for it myself, but I support people who do.
