Re: If British and Islamic values are incompatible, why do you want to live there?
Honor Killings, foreced marriages, etc. are unlawful in most countries. Only that the law is applied selectively.
As long as people are not discriminating others, hurting others, fulfilling their civic duties, following the law and paying their social dues, there shouldn’t be a problem with how they like to dress or what they like to eat.
If you are so proud of your freedom and liberties, why not let Pakistani/Indian communities live the way they want to? Hypocrisy would be if these communities migrate to the west and then break their laws (which we often do, but that’s a legal matter and not related to values).
Islamic countries do not publicize ‘freedom’ and ‘liberty’ as their fundamental values, so this might not apply to these countries.
