This is one of the biggest issues. What we really need is a good path to citizenship for people like this. Bring them into the system and get more of them paying taxes.
I had heard a claim about this recently, so I googled the exact sequence of words 'illegal immigrants pay more taxes', and as the top result, quoted in a box within the google page itself (as it sometimes does), was the following:
Donald Trump may not have paid federal income taxes for 20 years, but the undocumented immigrants he rails against certainly have, according to the head of a Latino civic engagement organization. ... Undocumented immigrants pay $12 billion of taxes every single year. They pay their taxes.Oct 2, 2016

The actual article goes into a lot more detail, and yeah, there are illegal immigrants who are not paying taxes, but it really is quite amazing, that there are illegal immigrants who are paying taxes for benefits that they themselves cannot avail. The contrast the article made in that paragraph to Trump, who proudly insinuated(?) that he had not paid income tax for 20 years is pretty funny

And yeah, plans for a muslim registry, which apparently are in discussion now would absolutely would be racist as well as xenophobic (and yes, racist, despite the "BUT MUSLIMS ARE NOT A RACE!" counterclaim that so often comes up. The registry would be for immigrants from muslim countries, so "brown people". And I don't think someone having converted to Christianity would suddenly make it okay for them to skip being registered), so it isn't conjecture, or stuff that he said years ago, or stuff that he just said crassly to be more populist.
Anyhow, a bit off-topic, or maybe not, but it is very interesting to me how in recent years as a response to accusations of racism towards a third party, some people bring up "We have to be more tolerant of peoples' differing opinions!"
Even in this election, part of the post-election conversation was "It was so obvious that Trump won! You shut all these people out! What did you expect would happen! You need dialogue!", exemplified by that irritatingly jarring fake interview video that kept autoplaying a couple pages back.
And that's interesting, because my understanding of most responses to racism have always been:
1) If it is a criminal offense, report it
2) Otherwise, if it is from an unrelated or not closely related party (some other group), you exclaim the wrongness openly, mock it perhaps, so that society as a whole would not come under the impression that it is okay, and the people would hopefully shut up with embarrassment- like most people were doing with Trump's supporters
3) If it is someone you know, and could possibly influence (your kid?), explain to them in no uncertain terms what they did is wrong
4) If it is out of your control (your parents, grandparents, relatives), ignore it, or passively show your displeasure
These people are suggesting a third option, which is "dialogue". I am very curious how this dialogue would go. For every racist person, you'd introduce them to a nice person from the race they were racist towards?
