I have just realised that it is a highly conservative and radical Christian event organised by Polish Catholic church and Christian right.
It has nothing to do with bringing up tolerance and people together. It is just about bringing up Catholics together.
Poland is currently leading as one of the worst countries in EU when it comes to discrimination of LGBTQ community (anti gay rights), anti emigrant, women's rights and free journalism, since the government has been dominated by ultra conservative, right wing Christian party (supported by half of Polish population)
