How much is tiny? We're talking several hundred million that believe these type of attacks are acceptable

Source?

Another false flag attack backed by the elites? 9/11 and numerous false flag attacks backed by the elites to create shock and fear within society. Fear is the instrument the elites use to control society.

Here's a doc from the BBC - the most liberal media outlet in the world.  And this is just what UK Muslims think.  There's a copy/paste a few pages prior here on what international muslims believe.

I thought it was obvious as to what the UK/Western democracies should do.

The above poll and plently of other polls shows a high percentage share religiously motivated attack acceptable, people shouldn't be calling for a muslism ban but don't bury your head in the sand either, this naive attitude is hurting hard honest working muslims.

and how many western people would support the failed airstrikes on syrian hospitals/weddings when asked? hundreds of millions of people

What do you suggest?  Allow isis to conquer country after country holding millions of innocent people hostage?  Is that better?

Integration, better education (for everyone), increasing the acceptance of all religions, fighting youth unemployment, destroying ISIS and hoping that the next terror organisation won't be as popular and professional, increasing the standard of living in those problematic regions etc.

Nothing has worked so far because A: it takes quite some time and B: it takes a lot of effort and money. The path is correct but there's too much talking going on and too few actions.

Not comparing a like for a like there are we? keep that head buried.
