Fix the motivation
Parking the absolute stupidity of Mays ambition maybe she should spend more time examining the motivation of the people that commit these atrocities
Back in the days of the IRA we knew what their aim was, a re-united Ireland. They were able, initially, to get a toehold in the then massively discriminated against Catholic population. Their method, wage a guerilla war against the 'occupiers' and 'oppressors' until the public and the gov't had had enough and gave them what they wanted. As a purely military campaign it failed as the vast majority of similar situations do. The two sides grind each other down to a stalemate, the original minority community also becomes sick and tired of the violence and talks follow.
What the hell do these guys want? Revenge, Sharia laws, Caliphates
We are constantly told 'Islamic fundamentalists' hate us and our values, which is a very convenient simple mantra. We are also told they have been 'radicalised', a phrase which easily transmutes into made more religious but in a bad way. I prefer the term brainwashed.
The brainwashers are a bunch of older men pushing an extreme version of a religion and they cannot tolerate any serious criticism. Because like Galileos Catholic church once one chink in the 'truth' is disproved the whole edifice may come crashing down. What these guys want is power and their version of truth slavishly adopted by everyone on pain of death.
Sadly like most true believers, these guys are so blinded by 'faith' they cannot be argued with or dissuaded. The best we can hope for is they die off soon taking their poison with them. Meanwhile we do all we can to counter thier propaganda.
In my book anyone who sees other groups of human beings as less than human and calls for their destruction is a fascist. just like Hitler, Pol Pot and countless others with ideologies throughout history. So let's stop calling them religious fundamentalists they are no more religious fundamentalists than an IRA bomber who took communion.
