[@Andreyich] ...dude, you literally just admitted to racism. And you don't care? Shouldn't who the Belarusian girl loves be more important than "preserving her culture?" She's "supposed," so she can't be Belarusian if she doesn't keep the bloodline pure? I can't really understand valuing the forced continuation of a culture as opposed to allowing people to cultivate their own happiness. But I'm guessing I can't change your mind. 

My girlfriend is Polish and I'm Italian. Am I a traitor to my race? Are we both? Just a hypothetical question.

Also, it seems that the most prominent dictionaries have updated their meanings.
