The reason given was that it is hard to guarantee safety of the protesters because of the anti-gay protesters there as well blah, blah, blah... rubbish anyway.

Besides these parades did happen anyway and were protected by the police - so much about the whole thing.

I have nothing against those parades, unless it turns into something like in Berlin ( I don't like any mockery).

As it was said by Josef Pilsudski - 'in Poland you cannot rule with a lash' - extremists is a marigin here and the whole story about the 'rise of nationalism/xenophobia' here is a joke.
BTW If I am correct Poland is the only one country in the EU where so called hate crimes are on steady fall from small level already.
