I would say alot of people in Ireland myself included support a tougher stance against Islamization yet would not want to be seen publicly at a Pegida march and be labelled a neo nazi by the majority.
So what's the answer brother? If you aren't willing to get vocal for something? In the US, "racist" was wielded as an effective weapon. But it became overused and debased. Now, I get called a racist daily and it has zero effect on my life.
If western civilization is worth fighting for, it's certainly worth the risk of "being labeled"
Plus, Pegida could probably use an impressive mountain of muscle (no homo) such as yourself. Heck, they appear to already have Dave. Bring some chicks into the light.
