On the intensity you certainly have a point, but on rate, I was recently surprised to see that between 2016 and 2017 there were 970 recorded offenses in England and Wales relating to a 2009 law criminalizing production or possession of a category of Japanese hentai manga. Agree with the law or not, that's a huge number, especially for a topic which is, to the say the least, vigorously debated. For comparison, a similar law in the U.S. was stricken down as unconstitutional (to my knowledge) in Ashcroft v. Free Speech Alliance.

Maybe not to our own people.

Did the UK/US not invade Iraq/Afghanistan, are we not still there? How many governments have we overthrown? How many people have we unjustly imprisoned/killed?

It's not a 1 to 1 type comparison but in my mind it's hard to imagine the US wasn't the most cruel or barbarous civilization in the past 80 years or so.
