//I cant see it a bad thing trying to preserve our heritage and traditions//
May I suggest that you try reading some of our history and you will realise that we have always been a nation of immigrants, Picts, Saxons, Vikings, Normans, Hugenots, Jewish, Dutch, Polish, Eastern European, and so it goes on - so your so-called heritage is more than likely to be the most exotic cocktail of immigrants and then you want to "criticise" the arrival of new culture.
Also, some reflection on change management/psychology may be beneficial and build a better sense of realism and tolerance.
