Are religious evangelizers of any religion, by def'n & intent religious extremists & potential terrorists?

Question

eg the religious Christian right, the Taliban, the Sunni Wahabists, orthodox Jews(they killed Rabin) etc

Answer 1

I think so, in a way. For example, you have those Evangelical preachers railing against abortion--and then some Evangelical Christian blows up an abortion clinic--technically an act of terrorism. I think that every person in authority who goes to the extreme has the potential to be a terrorist, or to create terrorists. So, yes.

Answer 2

In some religions, the extremists just sit around and pray all day.  Certainly the ones you listed have had examples, but there are many religions that don't blow anything up.
