With debates about immigration being stretched thin and rehashing the same arguments ad nauseum, it's no surprise we've come across comparisons to the Holocaust many times by now. In fact it's become a go-to defense for those in favour of immigration. But I think this needs proper support rather than being thrown into the discussion as an ace in the hole never to be questioned. There are some vague comparisons like xenophobia and racism, the scapegoating during poverty and so on. Yet these positions miss the glaringly obvious differences.
First, it is not fair to equate these two as Muslims are not an ethnicity but an ideology, and one which (based on Pew polling at least) is followed quite dogmatically in ME, Africa, Indonesia (some of which are sources of this immigration). The Nazi position on Jews was based on race myths and scapegoating for the loss of WW1. What is the current analog?
Second, the Jews are now subject not only to the possibility of NeoNazi racism, but Islamofascist racism and Jew-baiting. This is one of those vile ironies of history where two opposing racist and right-wing groups have a lot in common due to a common enemy. In some ways Muslims can be the aggressors, calling for Fatwas against novelists, threatening apostates with death, killing film makers they don't like, making terrorist attacks and threats against cartoonists in foreign countries and so on. It's also quite possible that Muslims would attempt to carry out attacks specifically against Jews (which have already been reported in Malmo). Yet the Jews didn't do these things, did they? It appears the comparison falls apart when you take a closer look, and when you're prepared to admit that different religions/ethnicities/cultures have significant and objective differences.
So I don't think it's fair to bring up the holocaust in the discussion on the European immigrant crisis. The Jews were accused of all sorts of things, yet these were fabrications and race myths. The reality is their current-day immigrant counterparts do have a much higher rate of crime, and their fundamentalists have carried out theocratic-fascist attacks on western liberalism, and are ultimately more comparable to the Nazis themselves than their Jewish victims.
Keep in mind nowhere do I say or intend to mean that "all brown people do/believe X". I urge you to take note that these are some members, but a significant portion of the group. Also that I'm not focused on discussing whether Muslims believe 'X' and whatnot, but that comparing the situation with Muslims in Europe to Jews during the Holocaust is too simplistic and doesn't work. With all that said, I don't know the whole story, so bring up any points you think are valid. Perhaps you have some ideas that work better than mine, or that counter what I've said and provide the opposing side a better argument.
