@Velund, this thread isn't about the RuSSian invasion of Ukraine.
What law defines the possibility of offending the religious feelings of believers depending on the term of the confession's presence in Poland
There's no such law. That's not what jon357 wrote about, neither did you, so stop manipulating.
what is the term for priority treatment of a confession by the authorities?
Tradition? :) (I mean the Presidents wishes and lightning candles for Hanukkah in the Parliament and stuff like that)
Don't tell me that politicians decide this privately and according to the current political conjuncture.
The tradition of lightning the candles for Hanukkah at the presidential palace was started by Aleksander Kwaśniewski and it was continued by all the later presidents. Kwaśniewski was also visiting Polish Tatars. Hanukkah candles have been also lit in the Polish Parliament for the last 17 years or so.
So, it is not regulated by law at all, and politicians/judges decide privately, who can have their religious feeling offended, and who is not?
No, of course not. Why are you confusing two different issues?
You asked why Hanukkah candles are being lit at the Polish Parliament. And you got your answer. In case of the law about offending religious feelings no religion gets a preferential treatment.
