It's their right as a sovereign nation to accept or refuse whoever they wish. The matter at hand is a loss of sovereignty and national identity due to little or no border control coupled with immigrants who do not wish to assimilate into a new culture. If course, it didn't bode well when the majority of the population infiltrating are military age males.

The Bulgarian authorities reported piles of passports and other identification documents, most of which were not from Syria which was where the news would have you believe the immigrants were from. The news wasn't carried much because it (the truth) didn't support the narrative. An alarm should have sounded when a number were recorded from multiple locations stating that they were coming to conquer the Europeans. Such people should never have been allowed in and several terrorist attacks later, questions are being asked and actions taken. Radical indeed.

If they are legally permitted by their own laws, then they can do as they wish; it matters very little to me what they think or how they act.
