I was about to post something similar: Anything termed "anti-" is mostly instantly tainted. To wit, the PEGIDA folks don't much care about islam, as long as it stays home. They just don't want it encroaching on *their* home. Simple and logical, really.
The scales tipped too far... the 'good's' in the balance. No outside influence and cultures become ingrown and stagnant... too much - they die. Merkel's and the European elites are wrong... they went too far.
