i don't think there's anything wrong with being proud of your heritage... it's like being proud of your family line. nobody's proud of being a certain color skin, obviously they're proud of their background and heritage.
the one thing that pissed me off personally is people who live in a country but refuse to learn the language, laws, customs, etc, and just continue doing their own shit as if they're still in their home country.
example- when i was living in aus and going to claim my welfare check every forthnight, i had to wait 2 hours in line cus half the fucking people there didn't speak english, couldn't be bothered learning english, so they needed a translator. now you need to be an aus citizen to claim welfare, so they were there 5 years minimum.
5 years and you couldn't learn basic english?? how the fuck do you expect to get a job, you gonna be on welfare for the rest of your fucking life! just a burden on tax payers.
this can be solved by a simple language test- fail, and ur on the first boat back.
oh and my the way, i'm an immigrant myself so i know what im talking about
