>Welcome to our country, Jew! We have certain customs, ways of doing things, we eat certain foods, we have a certain religion, etc. Surely, since you live here now, you will convert and adopt our ways and begin to assimilate. After all, we need some genetic variation in our population. So, welcome! What say you?
>Oy vey, no, I think I will not convert and try to assimilate and adopt your ways! Instead I shall continue to practice my own religion and customs, and eat my own food, and do things in my own way! And I will make more people who look, talk, and act like me, and we will grow in numbers, eventually needing more land to live upon. When this occurs, we will have to take over the land from whomever was previously living on it. In short, we are, by virtue of calling ourselves something different than you, and continuing to act differently, in competition with you!
>Hmm… Well that's a bit of a problem now, isn't it?
