I'm sorry you feel so negatively about the UK and the EU. Many people quite like living there. Also, if you see Fox as a centrist news source, that may be a sign that you should recalibrate. Fox is neither: right rather than centrist, entertainment instead of news (as they announced in court).
Well, unless you're their Imam, you probably don't get to define being a good Muslim for them. But the Bible is also full of rules that modern Christians and Jews mostly choose to regard as historical relics rather than central pieces of religion. The authors of the Torah felt that the prohibition against mixing plant and animal fibers was important enough to mention it twice (Leviticus 19:19 and Deuteronomy 22:11), but most Jews aren't bothered by it at all.
