calling for the assassination of a real person are punishbale offences under Polish law.
But not within a fictitious context. Calling for the assassination of a politician by standing up on a soap box is an offence but depending on the person doing it, even that may simply be downgraded to a public order offence, rather than incitement to murder.
violating people's relgious sentiments
So in that case, hard core pornographic magazines and movies shouldn't be for sale in Poland, nor should there be sex shops and Gabinet Eroticzny with large signage declaring their purpose. I don't know many observant Catholics who aren't offended by such things and remember that these things are clearly visible to children and we all have to see them, we don't have a choice in the matter. Plays, books etc are a matter of choice. One doesn't normally go to see a play without finding out a bit about it first and if, when you get there, you find that it offends you, you're free to leave. Quite frankly it boils down to common sense and people need to exercise that for themselves.
selective censorship respecting each side's sensibilties and taboos.
Empty waffle. Give an example. I'll help you out. I'm a producer who wants to stage a play about a young Catholic homosexual man struggling to come to terms with being gay. I go to the censorship board with it and they tell me it's offensive to Catholics, but you can stage it if his religion isn't mentioned, just tweak the script a bit to take the religious element out of it. But, we reply, it's the whole point of the play, the struggle between his sincere religious beliefs and his sexuality, his love of God which is deep and sincere and his confusion as to why God should have given him this cross to bear etc etc. No, says the censorship board, we have to respect the sensibilites and taboos of the majority of people of this country, Poland is still a Catholic country etc. Or imagine it's a play about domestic abuse. The man is a 'good Catholic', in church every Sunday and active in the parish but he beats his wife. No says the censorship board, you can't show a Catholic beating his wife.
However, I see no reason why theatres shouldn't have some kind of warning system on their posters and advertising material in the same way as TV programmes, 'this play contains scenes which some people may find disturbing or may offend religious sensibilities'. That way nobody will waste money on a ticket or be offended.
As far as films go there is already an adequate method of dealing with that, by grading the suitability according to age.
Then we move on to printed material. If you're going to introduce new censorship laws for plays, then you need to also control what people write. That means monitoring books and newspapers..........you're basically talking about a return to Poland in the Communist era and a far greater waste of taxpayer's money.
