First, I love how you got upvotes for saying, “I didn’t bother even trying to find any evidence before posting.” But that’s not on you.
Second, murders are usually followed up on in the developed world, at least to some degree.
Here’s a BBC article. 20% in the UK (I found other regions with higher amounts, but I’m okay with this one). Note also that we are talking about something that is incredibly unlikely. 30,000 deaths worldwide per year of women in relationships by their partners. Assuming half of adult women worldwide are in relationships and noting there are about 6 billion adults gives 1.5 billion women in relationships. Note that the country with the highest rate of singles for both sexes is at 25%, so this is pretty conservative. That is a 2 in a million chance per year. Assuming women are in relationships for 60 years because, why not, puts your risk at 120 in a million of being killed by a partner over your lifetime. That is about 1.2 in 10,000, which is about 10 times as likely as dying from general anesthetic.
So now that we’ve determined that 1.2 in 10,000 men are killing their partners, and I will happily acknowledge that domestic violence is much more prevalent as long as you acknowledge that depending on region, 40% of victims of spousal violence are men (279000÷(432000+279000)), why would we waste our time targeting men for awareness of spousal violence when most men aren’t doing it and a significant part of the people who are doing it aren’t men?
This is pretty much me. Used RIF, when it stopped working, I stopped going there regularly. Took a couple weeks to completely kick the habit, and a year of occasional use via search engines, never even bothering to log in. Now I almost never go there. I’ll head there as a last resort if a search engine can’t find me a useful alternative for what I’m looking for.
