the only such square that miraculously escaped wartime destruction.
Have you ever been to pl. Zbawiciela in Warsaw? (Note to mods: that's the 'Saviour Square' mentioned in the title of this thread, making the question very much on topic.) You very much appear not to have ever been there. Only one building on the entire 'square' is in its pre-1939 form, and that one was reconstructed in the 1950s. Of the rest, two are reconstructed buildings based on the pre-1939 structures, one is an office block from 2005 (the top two floors being all glass & steel is a bit of a give-away) that recycles architectural elements of an older building. The remaining four buildings are pure socialist-realist, build as part of the MDM development and not even vaguely related to the pre-war buildings that were there.
No wonder you are having such problems with seeing what happens in Warsaw if you never bother going to have a look!
Although police dogs do attack on command.
Actually, they don't. Police dogs (in Poland) are trained to detain, not to attack. Training them to do otherwise would break Polish and European law. I know that in your country county have armoured tactical assault weapons, but here in Europe we do things differently. There are not now and there never have been any attack dogs guarding the rainbow in pl. Zbawiciela. There have never been any dogs guarding the rainbow in pl Zbawiciela round the clock. Just as it has never been guarded round the clock by riot police, despite your laughable claim that it is guarded round the clock by riot police with attack dogs.
They should set it up in front of Gronkowiec's town hall if she likes it so much. Except local residents wouldn't stand for it any more than those living in and around Saviour Square.
I happen to live just round the corner from the town hall and would most certainly welcome the rainbow; it would certainly brighten up pl Bankowy. I can't imagine that anybody I know who lives near there would object to it being there, I certainly saw enough locals at the last Warsaw pride parade.
But then I have never met anybody who objected to it being in pl. Zbawiciela. The most of the people who objected to it have no idea what a rainbow signifies, have never been to pl Zbawiciela and use the whole thing to tell pointless lies.
