Okay, so I'm generally a sceptic in life whereas you are a natural optimist. I can accept that. But I think you misunderstand me slightly - I don't want Sharia law to take over the UK, but current demographics seem to point towards a possibility of that in the future, unless there are future unknown changes.
Citing how the Irish suffered various discrimination in the past doesn't really cut it. It always seems a cop out to cite a past example of something to deny a current-day problem. The context is different. The problem is different. Globalism may engulf Britain (and Ireland, and the whole of Europe) completely. This is the worry of many people.
For example, how can you have a functioning welfare state when the gates are open to the whole world? You can't - it's financially unsustainable. Most of Africa (1.2 billion) would prefer to live in Europe (Germany and the UK especially) because of our generous welfare state that would instantly put a roof over their heads and provide them with free money and everything they need to live a batter life. If I was an African, I would want to jump aboard this gravy train also - it's human nature to want to better yourself and your position in life etc - but it means it will kill off our welfare state and create a more American society - which no European wants.
Jeremy Corbyn recently said the Labour Party wants to help the 66 million refugees in the world. That's impossible. The current-day left care more for people outside Britain than those within. Globalism is all about dissolving and replacing societies with those willing to work harder for less.
