You make a good point, but there's a difference between maintaining a cultural identity so that you have ties to the old country, and fostering and festering ideals that are not at all in sync with modern culture.  To use your examples, should your neighbours be concerned if you want to play bagpipes, foster Scot's Irish in your children, wear your clan tartan, maintain a clan identity, compete in the Highland Games and support Celtic?  Probably not.

Should they be concerned if you think women should be second class citizens? Probably.
