Where have you seen this in "Germany, Sweden, or even the UK" (your words)? Can you give specific examples?
Sure, Dortmund, Berlin, and London. There were a tons of ninja women too. Plenty of young dudes just standing idly by the subway entrances especially just waiting for people to pickpocket, ask for money, women to try to pick up, etc. There's also tons of videos about this including one where a camera crew from a liberal station I believe CNN tried to interview the migrants in Sweden but they were all promptly attacked by migrants. Funny, they came to make a video showing that it's not all that bad in Sweden and migrants aren't causing any problems yet ended up getting beat up and chased away by migrants lolololol.
Do a quick google and you'll find many cases of social 'problems' resulting from unemployed or grey economy Poles in those countries.
At least they're not blowing people up, beheading German/British/Swedish/etc soldiers, mowing groups of people down with AKs, driving vans into crowds, or stabbing people for buying alcohol on a holiday.
One only needs to watch the Polish government's (specifically MFA's) video to understand the position of the Polish people and our democratically elected government:
youtube.com/watch?v=e4EHOk7T4QQ this video is very informative and I encourage everyone here to watch itOf course the vast majority of Muslim migrants AREN'T terrorists. However, a significant percentage reject the values of European society such as equality with women, separation of church and state, ability to buy/sell alcohol, etc. One only needs to read the studies which show the beliefs of various Muslim countries - i.e. Egypt, Afghanistan, Iraq, etc. The percentage of people that believe in Sharia law, that say suicide bombing is acceptable in certain circumstances, etc is appalling. 91% of Iraqis want to make sharia law the law of the land - and you wonder why there's people marching with Sharia4UK, Sharia4Belgium flags etc.
9% of Pakistanis and 14% of Nigerians have a FAVORABLE view of ISISand we wonder why there's nonstop terror attacks in Europe. And we're letting these people right into Europe and giving them food and housing too! Thankfully, not Poland though.

Until it happens
You can count on 2 fingers the amount of terror attacks in Poland. Now if you did the same with France, Germany, etc you'd run out of fingers and toes. And that's just terror attacks - everyday the residents in places like Calais fear for their safety and the women publicly go on TV begging the French government to do something
