This is waht I call action! Such Greeks are to be admired and supported – unlike many in the West, they still have the backbone to stand up for their national culture and heritage.
Where i live people are totally against mosques being built in their neighborhoods. Property values decline and crime inceases in the areas where the mosques are built.
Ironically even though the local council may deny permission for a mosque to be built, the Islamists appeal to a higher (socialist) court which usually over-rules the council and gives permission.
Whereas people here are conditioned to accept this rubbish and allow this unelected socialist court ride over the wishes of thousands of citizens, in Greece it wouldn't surprise me if a mob tore the mosque down (same as the Ayodiya sp? incident in India, years ago).
