We are family.
I am very happy that you think Polish people are not racist.
Some Polish must be racist, no?
I just think that sweeping statements are never true, I mean if you said that, of all the Polish people you met non were racist, that would be fine, but you say no Polish are racist, there is an assumption that you know all Polish people.
In fact there is something merriam-webster.com/dictionary/racist
1 : a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race
so you are actually being racist (not negative) about Polish people.
