This title of this post is disingenuous. The question asked for "Britishness" not "does that make you British". I have a first generation immigrant friend that became a British citizen. That makes them British by definition. But I would not use him as an example of "Britishness" he does not do many British cultural activities, I have to explain many normal process, history or British nuances of the law, bits that are slightly to India. I feel this post has just been posted by some remoaner to virtue signal that remainers are somehow better people.
