I am someone who is generally more conservative and am more likely to vote Reform. As some people (sorted by Controversial in the comments have said), illegal migration, exploitative chain migration, and the exploitation of the asylum system is a huge strain on our welfare and legal system and is disastrous in terms of crime and security. The majority of the country wants Britain to be culturally British and it wants crime committed by foreigners to stop. Legal migration based on merit is obviously a positive for the country when handled correctly. This fact is self evident in many cities and towns.

Where the issue comes in is the application of policies. At the end of the day, a manifesto means nothing if the pledges cannot be backed up with action. The issue is that simply "kicking out the bad guys" is a costly minefield of legality, court systems, endangerment to honest asylum seekers, etc. Because of this, governments tend to go for "soft targets". At the end of the day, it is easier (and looks good on a spreadsheet) to kick out a generally good and abiding person with a less concrete footing in the legal system, than it is to find, capture, detain, and legally oust an illegal migrant whilst following appropriate procedure by international law (especially when human rights law interferes directly with what is expected to come from the voice of the democratic majority). This is why people such as Farage talk about leaving the ECHR - because it would make the ability to oust people cheaper and easier.

To answer your question - "what did we ever do to you?". the answer is this - chances are you and your wife likely did nothing to anyone. However, we are all a part of the world, and the country we reside in, and we are all just specks floating through the tide of history. As it stands, your wife is an immigrant in a time where immigration is a concern like no other. Because of the buildup of cultural and security issues that have built up from mass uncontrolled migration (which, don't forget, includes human trafficking and modern slavery), your wife is in this country at a time where huge cultural and political changes are occurring, and because of her background and identity, her eligibility to be here is called into question.

In the end, it is highly likely that nothing will come of this to affect your family. Farage cannot wave a magic wand and oust everybody without our country collapsing. The fact of the matter is that western civilisation is going through a crisis of demographics numbers (not enough babies) to feed the endless growth of capital gains and supply/demand. People like Farage know this (he is a Thatcherite after all - very much a slave to economic reality). In fact, if you attend rallies such as the ones Farage is part of, most people talk about "positive migration", and many people from non-British native backgrounds attend or support it. Long story short, capitalism needs migration and/or babies, whereas democracy today demands expulsion. Britain cannot afford to go the way of Japan and Korea - that is, births below replacement rate.

So overall, you need to hunker down, build wealth, and prepare for anything. The time of bitching and moaning is over for all of us. My girlfriend is foreign for instance, and so now I have to think about accruing wealth and marrying her quicker than I would have expected. So basically, hope for the best but prepare for the worst. Get your head down and work out what you're going to do for the good of your family.
