What to do after Manchester? What to do after any of these attacks? Weep and post Facebook messages and memes and sadly admit it's the new normal? That is what is likely given what we have seen to date. The problem is, of course, we are hoist on our own petard of Democracy, Liberalism and inclusiveness. Our fatal flaws. But they should not be a suicide pact.
The Western world has to administer some zero tolerance and tough love. Left alone, Islam is not going to reform itself. So maybe we need to do it for them in the interest of national safety. Trump tried a relatively tame scheme and was roasted for it so how likely is it for anything with real teeth to succeed? Unlikely, of course.
We should start with zero tolerance for the Jihad. Laws should be passed that make incitement to violent Jihad a high crime punishable by long imprisonment and deportation where possible. This would include jihad preachers, social media posters, sellers of such material etc. Mosques which engage in the rhetoric should be closed and their preachers jailed. Internet providers and social media which allow such stuff should be made to pay for their collaboration by jail and or stiff monetary fines/restitution.
The perp in Manchester was "known to the police." As were almost all of the recent perps elsewhere. Lots of good it did under current laws. Perhaps if laws existed making possession of jihad materials highly illegal, these guys could have been in jail instead of killing people. As it is now, lawmakers have to wait until they kill first. Senseless.
There are hundreds of other thing which would also help but I can already see the hysteria that would erupt at even the few sensible suggestions I have made. Unfortunately, dead innocents is the price most governments are willing to pay to be seen as Liberal and Democratic. This applies everywhere, even in Israel which at least has the excuse of worrying about the International community's reactions to its self defense.
We don't need to demonize and punish Muslims; just those who would kill us or offer support for those who would.
