Nobody has said radical Islamicists are the only people who carry out terrorism. They're just the ones carrying out the overwhelming number of mass acts of terrorism around the globe in the last 20 years. I still don't understand how people can pretend otherwise, except as some kind of a 'yeah but

too' schoolground finger-pointing. This is way too serious of an issue to play dumb games like like.
Here's the wikipedia list of
fatal terrorist attacks. Go to the column on the right and filter by date, most recent at top. Then look at the political ideology column and scroll down over the last 20 years.
