Do you believe right-wing extremists pose more of a threat than ISIS extremists?

All extremists freak me out.

I have a problem with behavioural mapping programmes like Prevent, as I do with any predictive punative model.
At some point they will inevitably get it wrong, while my mind is cast towards the inexcusable stop and search powers which has become a tool of instutionalised racism within the police. 
Probability is a problem especially when applied to people, possibility even more so though a good mathematician could and should tell me that is wrong. 

But as to which extremist group is more dangerous we'll have to wait and see. (Possible adjunct? if right-wing extremists become part of the establishment, which is more dangerous then).

Interesting question, daydream. Thank you.

In Australia, there are some extremist white-supremacist groups. They work secretly because propagating hate and racism is illegal.

(Yes, I recognise the contradictions with things I've said before. Our government does not recognise the racism in its endless failures to fix problems in Aboriginal communities which are at least in part caused by its own bungling.)

An example. Nobody knew of a particular group operating down in Adelaide. But when Pauline Hansen first got elected to Parliament and gave her maiden speech, she publically declared that Aboriginals must not be given any advantages over whites through the welfare system and that all Muslim immigration should be banned. She said a lot of other blatantly racist things about almost every group that was not of British descent. 15% of Australians agreed with her. Within a week, an Aboriginal boy of seven was doused in petrol and set on fire. In the school playground, in front of all the other kids.

The boy, Jandamarra O'Shane, is the son of a famous liberal Aboriginal magistrate, from a family reknowned for its professional success and its political activism on behalf of Aboriginals. Jandamarra survived, but it was in intensive care for a long time. He required multiple surgeries to replace the burnt skin. Donations poured in from all over Australia, especially from whites.

When police tracked down the perpetrator, it turned out to be a teenager from the group in Adelaide, who had traveled half-way across the continent to perpetrate that crime. When asked why, he answered that Hansen's speech had proved to his group that now was the time to come out in the open. He was convicted and sent to prison. This happened back in 1996.

In my view, this story illustrates why we do need to be vigilant about extremism.

Take a map of highlighted crime-ridden areas and notice all the are infested with leftist-extremists are highlighted, then maybe rethink the question.

 Areas with so-called right-wing extremists are typically low in crime.

Not denying there are dangerous people when in comes to extremists of any brand but just look at the number of murders in Chicago in any given year since the turn of the century and tell me who poses the biggest threat, It is rather obvious, yet no one wants to own it. It belongs to the left-wing obviously and has the potential of being more dangerous than Isis and has probably already claimed more American lives. Chicago alone is all you really have to look into, we can look at NYC, L.A., D.C. and all the other areas controlled by the dems and see their 'tolerance' and policies attracts crime.

 I am not for either major party but the whole democratic philosophy actually promotes violence by allowing thugs to go armed and often unpunished while law-abiding citizens are forbidden to protect themselves according to the second-amendment and are often afraid to even report crime or suspicious activity since political correctness reigns in these areas allowing criminals a free-pass.

 Think about it, you are a criminal; would you target a gun-free zone or an area you were likely to die if you attack another human being? Many laws are set up to protect criminals in highly populated areas because they make up such a huge part of the population.

 If right-wing extremists, and that term is used incorrectly often, decide to become dangerous it could be very damaging but with the exception of very few who forgot their meds,  they have no intention of doing harm. Millions of guns are owned by right-wingers and some left-wingers here in the south as well. We are here to protect ourselves, our friends, family and neighbors from harm. If anyone gives us a reason to fight, we surely will but it's the last thing on our agenda.

 To compare right-wing extremist to ISIS while the bottom-of-the-barrel libs are going around destroying the country and committing domestic terrorism is something I can't understand. How do you even come up with this stuff?

Look at what the left wing anti-Trump criminals, errr protesters are doing.
Look at groups like BLM "pigs in a blanket, Fry 'em like bacon" 
The crime in cities like Chicago and other Democrat strongholds. 

No right wing extremists are not as dangerous as ISIS....when they start lining people up and cutting heads off and putting the on a pole, locking people of other faiths in a cage and throwing then in the water, raping women and children so much that the US government excuses it as just culture. Etc.  Then maybe you can compare right wing to ISIS.
