She told my friend in Polish which my friend translated later.she also asked my friend if I knew what a straightener was cause for her she finds straight hair "perfect".
Typical polish, they are all racist tbh.. Now you've mentioned her nationality it all makes sense.
Be polite towards her, but get your friend to tell her that you know she is prejudiced towards you. If she gets openly offensive, I'd call her out on it
If 90% of white people are racist there'd be no black people brown people. Anywhere. Most white people are probably just unaware of or indifferent to racism. But actually racist, no. In fact, the statement you made was rather racist.
