You are not making any sense, yes their core message matters as they are trying to campaign themselves to the people. And if people see flaws within their message, they will not give them their support. There are any flaws within IS and Far Right agenda, and they both know that, so what do they do? Force themselves unto people either by violence or spreading around hatred. Far Right world revolves around Muslims, Islam and migrants. The reason is to force themselves unto European people. They don't actually hate Muslims that severely. But they keep propagating such message to assert themselves into position of authority.
So doesn't matter what issue is being discussed by politicians, whether environmental, social, or foreign affairs related. They respond with focus on Muslims blah blah blah. To discredit the opposition and basically force them to shut up. Eventually because they are so loud, they silence other voices, and this is their way of reaching power. Once they reach power, they will discriminate against everyone that isn't part of their club and distribute resources amongst themselves. And if anyone question such corruption or strange policies, they will hit them with being collaborator of Muslims or something. You clearly don't understand their strategy and approach.
It is a lazy and lame one, nothing impressive about it. Daesh does same thing in Middle East, try to force themselves unto the people who never asked for them in the first place.
Actually it is a Sunni thing. But, only reason I brought it up is because Daesh and their supporters think their Caliph is rightly guided person who will restore Caliphate. Some of them go as far to claim he is the Mahdi. He is neither rightly guided nor will succeed in being anything similar to what historical Islamic rightly guided figures were. THat's why I said in our time, the Mahdi will be that figure and he will not approach matters like they do.
You are not supposed to be waiting for anyone. But, that doesn't mean agree with Khawarij or their approach which is reckless and will bring Middle east back to stone age. You need rightly guided people to lead Middle East out of the mess it is in and bring about prosperity and establishment of Islam. And those Khwarij are not the people for it.
