Polish Tatars lived in Poland for hundreds of years and at this point are not really Tatars anymore, they look European. They are Tatars only by religion and their mixed Polish-Tatar names and surnames. Kashubs have also lived in Poland for over a thousand years and have had mixed marriages with Poles, all of them speak Polish and were born in Poland plus their culture is basically the same as Polish. This is not similar in anyway to what the guy above stated about "not speaking polish, visiting poland on vacation, and having a polish passport given to him in adulthood".
The difference you should make clear is asking if someone is Nationally considered "Polish" based off of a National passport. Simply saying "I'm Polish" includes Ethnicity too. This is the average American style of thinking because American is not an ethnicity.
And yes, many of them because I have an accept when speaking Polish, the women on dating sites with Polish writing being anal about it.
Yes every woman on the dating sites you use should be happy to speak with someone using broken google translator polish without the proper letters simply because you haven't learned the language, while having your entire life to do so :)
