Bullshit.
Why oh why do the left consistently go against the overwhelming majority of the populace?
That the majority of a populace happen to share an opinion is no guide to whether it is in any way valid or not. In fact, if public opinion was invariably correct, then politicians would have no serious role to play and government could be conducted by a combination of opinion pollsters and bureaucrats.
In this instance, it is also probably safe to assume that the majority of people lack a sufficient knowledge of the relevant jurisprudence, the psychology of radicalisation, neuroscience (as it relates to the development of the teenage brain), the role that women played in ISIS controlled territory when they had a lot more of it (Patrick Cockburn wrote some very chilling articles about that), and the nature of moral agency as an aspect of the free-will versus determinism debate, in order to make a reasonably well-informed judgement call.
It might be worth pointing out with respect to that aforementioned debate that - although our justice system and daily interactions are predicated on it - the arguments for free-will are distressingly thin. See David Eagleman and Daniel Werner for the finer detail.
Additionally, as Jonathan Haidt has demonstrated, our moral and political opinions are predicated on instantaneous gut feelings more than anything else, intuitions which we then tend to bolster with post hoc rationalisations. They are also remarkably impervious to modification, as Professor Drew Westen showed in his study of supporters of John Kerry and George Bush described here:

Unsurprisingly, Westen goes on to say this in his book The Political Brain : ‘The data from political science is clear, people vote for the candidate who elicits the right feelings, not the candidate who presents the best arguments.’
This last observation is one that I should bear in mind the next time I contemplate contributing to a political thread on here that is already going round in circles.
