yes you did, do you really think CC differs greatly from the real world when it comes to domestic violence, its now a hidden crime, with no signs of declining....CC isn't the moral bastion of the internet, where its poster do none of the evils of the real world but I might have been a tad dramatic with the suggestion of half but I've no doubt the percentage would still be on the high side.
About 1.3 million female victim cases of domestic violence, and 716000 male victim cases for the year ending March 2016 These are also ALL domestic abuse cases. Since you're comparing to Mayweather, we can take 75% which are the violent cases. So 1.75 million violent cases
The UK population aged 15 and over (this is as close to adults from ONS data), has the population at just over 15.5 million.
1.75 million victims is 11% of the adult population.
Since 83% of domestic violence abusers have a previous conviction, that accounts for roughly 25% of the UK population.
ALL registered users here are around 40000, that's only 4400 of ALL users ever registered to CC. Since only 25% of the population have a prior criminal offence, those 4400 cases on CC are likely to be committed by 1100 users.
1100 users out of all registered members is actually tiny. 3% in fact. So I'd disagree with you that the percentages would be on the high side. If every post in this thread was made by a unique poster, there would only be 2 offenders.
The real world, and stats disagree with you.
