Do note the timeline. Up to 2015 the governments of Poland were largely liberal. The current ruling party's conservative coalition from 2005 collapsed under its own weight in two years. You're judging the whole situation through the lens of the actions of a single political party, which came into power only because as liberal as liberals might be, they were sort of okay with having a sizeable disenfranchised minority in the country.
