Don't you , you probably were not old enough to know.Repeatedly saying 'you don't think things through' and making personal insults does nothing for your case.
I can assure you I do think things through.
The IRA killed far more Brits than Islamic terrorists have. I was evacuated from school because of an IRA bomb. I don't remember us blaming the Irish people or stopping Irish immigration or closing the borders or withdrawing up our own backsides in fear
Isis is a 50 year war.
Again you just don't think things through.
