On Romani culture: it's a daisies twisted mess and it's hard to understand without being personally confronted with it, which can be quite a shock. That said, I haven't studied the subject but I'm familiar with some of the persecution they faced throughout history, and it seems likely that that originated or at least exacerbated the problem.

How is plain islam a worst threat than, say, catholicism? It's actually more liberal on some points. The real threat is fundamentalism and that is not limited to any religious group.
I think the problem is the spread of fundamentalism through islam and it's undeniable growing influence. That's not to say you should judge someone solely on their religion though.
Immigration is quite a complex economical and socio-cultural issue, and there are legitimate reasons to want to limit immigration and put restrictions on it that have nothing to do with racism. I personally agree in spirit with the language and culture tests imposed on immigrants in my country, precisely to promote multiculturalism and avoid segregation.
But wanting to completely cut off immigration or limit it to only immigrants that benefit your country (eg. skilled labourers) is pretty selfish, considering some of the hellholes and persecution people are unfortunately born into.
