They are talking about 750.000 if that is correct i canīt say. Itīs on the news every Night. They have not enough facilities for these people and a lot are sleeping on the streets or in Tents. They are given Vouchers to sleep in a Hotel but it showed on TV that most Hotels wonīt take them for various reasons, one Hotel was intervied and said i am still waiting 6 months for my money so i will take no more in my Hotel. they will have to integrate them, teach them a trade...for what job? Jobs are scarce here for Germans. The hate is starting here because Germans are being cut to pay for all this. Not all the protesters are Nazis. However look at History that is how it began
The "Nazi" description is just a way to quite people down. If they are labeled as such, especially in Germany, they quiet down. I see however, it may have reached a tipping point and people don't care. Maybe PEGIDA picks up some steam again.
To the last sentence, yes you're right. They thought the Jews were overtaking their culture and not assimilating. History should remember what happens when you piss of 60 million Germans. I assume though, they are going to import them so fast that it dilutes the native population. I'm surprised to see that polls show such high acceptance of these people though. Maybe Europe truly is doomed. :/
