OK, but unless I am misinformed, PiS is not suggesting to annihilate those groups?
It always starts from stigmatising and enmity, annihilation comes later as a natural consequence when most people are so brainwashed they are ready to close an eye and keep silent when murderers do their job.
That is why hundreds of people who survived WW2 and are still alive, during various conferences, meetings, marches, demonstrations etc warn the society not to allow second nazism to be born in Poland.
Here, despite PiS gigantic brainwashing in state media, nearly half people voted against them. That is a very positive factor in that unpleasant situation we are experiencing with the right in power.
