The EU has been perfectly transparent about all your grievances you listed. Every joining member knew full well what they are getting into and that membership in the club comes with giving up sovereign rights.
What these countries are saying is a giant fuck you to the unelected traitors that make the decisions at the EU. You can kiss these countries goodbye from the failing bloc. This is their ticket out. Fuck you left wing nut jobs - we aren't going to bring in people who want to kill us. We got our own problems. 'But you signed a contract'. Lol.
Each last European official holds elected office. You may want to read up on governance in the European Union. Traitors? So far most European feel well represented and well served. At the very least most European officials still understand the concept of civil SERVANT something that seems completely lost on most US or UK officials. Even if Poland and Hungary left the union (which they of course won't because they receive lavish hand outs from Germany, France, and other countries) it won't be a loss to the EU if those countries are unwilling to contribute their fair share. They already do not pay in a penny, net-net, nor do they contribute in any other meaningful ways. They joined because the people in those countries wanted in. They can change their mind any time nobody holds them back. I am not sure why you make this personal, why do I need to fuck myself? Nobody wants to kill us other than a tiny number of nut jobs. And it is our job and the job of our law enforcement to sort out those bad apples and bring them to justice and evict them. Simple as that. Not sure why you are so angry.
Fuck you left wing nuts - that's what the Eastern Euro bloc is saying to the EU and their horrible plans. I'm not saying that to you. Why do arrogant big govvie Leftists think everything is about them? Huge ego. Anyways - if you think these countries signed up to bring in a gang of murderous people who don't want to assimilate into their country - well you don't understand these people (Hungarians, Czechs, Poles,). They likely will never allow this. That is not what they signed up for and hopefully they retain the backbone and continue to tell the EU to stick it where the sun don't shine. I wonder why Budapest, Prague, Warsaw have seen no terrorist attacks in the last few years? Imagine telling a sovereign nation that they have to let in murdeous zealots...or else? THe arrogance...
This is not new. Muslim invaders have tried in the past several times to take over Western Europe. The question today is - who is the next Martel?
