Some things that are being deliberately ignored by some on this thread.
The situation of the Jewish in the 30s was very different because Israel did not exist. There was no Jewish homeland. Jews only existed as minorities in countries where they were hosted by majorities of other religions, and also often had no long standing geographical ties, for over 1000 years. They had a history of fairly regularly being moved on and ejected from countries. They were always the minority and had little power either to change things in the country they were in or resist persecution and oppression simply because their lack of numbers always left them pretty powerless. They almost always depended on the toleration of others simply to exist.
And as such they were always a persecuted minority with little power to protect themselves or change things. As people have repeatedly said, taking those who face a specific threat is very different from taking the generalised population of a country because it's at war and as a result importing said war to your own shores.
That moves onto a second point: in the 1930s Jews were not blowing up airports. They were not blowing up subway stations or marathons or football matches or buses or nightclubs or coffee shops. They weren't shooting people in restaurants, offices, theatres, museums, concert halls or on beaches. They weren't beheading people in the streets. They weren't besieging shopping centres or hotels or theatres. They weren't kidnapping hundreds of schoolgirls. They weren't taking control of governments and suppressing other religions and closing their places of worship (Indonesia), or controlling states where acts of appalling violence and oppression were committed against women and minorities (Saudi, Brunei etc, etc, etc). They never had significant numbers publicly declaring a wish to spread their religion forcibly worldwide nor publicly and repeatedly announce their intention to oppress and murder others simply because they choose not to believe the same as them. They weren't engaging in their own centuries old bloody sectarian wars nor violently attacking their own minority sects.
Their entire worldwide population is significantly less than the population of Syria. They were not the dominant religion of almost half the world. They were not engaged in brutal oppression of others in the parts of the world they did control.
In terms of the threat to the security and safety of the people already here, and the power and will to pose any real threat to the safety of others, Jews in the 1930s can't seriously be compared to huge numbers of Muslims.
And yes I know not all Muslims are extremists, blah, blah, blah. But we know that large enough numbers are for serious problems to be happening across the world as a result.
And as I have said repeatedly. If you simply import the problems which people are running away from, you give nobody asylum. You just put more people at risk.
