I'm genuinely curious, has it really? I wonder if it's just more widely reported?
I tried looking up terrorism statistics and found this: https://ourworldindata.org/terrorism
For most countries, it doesn't look like much has changed from 1970-2017.
I glanced at hate crime stats on the FBI website (just looking at 2008 and 2017), with 7,783 and 7,175 crimes reported for each year). So not much change there either.
Obviously this is a half-assed attempt, but I just wanted to counter the idea that the world is falling apart. Hopefully someone who has more interest in these things can provide some studies with more comprehensive statistics.
