I can't tell if you are being serious here. Are you saying only wahhabists promote terror? Now I personally believe that Saudi Arabia is the largest state sponsor of terror, but Iran is usually identified as that country and they don't believe in wahhabism.I've never come across that. My muslim co-workers are no different to any of the others in that respect.
And yes, whilst Islam might be a quarter of the worlds population, Wahhabism is 0.5% of that.
