I must admit my gut reaction (simplistic over reaction no doubt,) would be to burn more of them, then wait for the backlash and then burn even more of them, rise and repeat untill they cant cope with the elevated stress levels anymore or just find themselves looking increasingly ridiculous and give up the ranting and overreacting.
Yes i know it wouldnt work as many innocent bystanders would be beheaded, ..but This i do know, giving in, tippy toeing around to avoid offense and being all PC just to prevent the overreactions just appears to be rewarding bad behaviour.
