Of course you do. In America on a smaller scale than 9/11 of course, there is still an active KKK, there are also other antisemetic movements, huge amounts of attacks on abortion clinics (Army of God). In India a christian terrorist group deliberately set out to murder groups of hindus a couple of years ago. Its just not widely publicised. There are lots of very crazy right wing groups based in Europe, that may not have stretched to terrorism,yet, but it could happen. Look what happened to Jeremiah Duggan.
There is just too much hate around.
