Because it is a loaded question (check the wording) that also mostly backfired.
I voted remain. But the brexiteer argument was that the EU is NOT just a trading bloc and has conspiratorial designs on further reduction in national sovereignty. Indeed the EU commission are seeking this right now and have plans to campaign for it.
The remain campaigners and media denied this. They denied even that the EU wanted a military.
The responses to my question indicate that these people support further reductions in national sovereignty to be handed over to EUP and EUC. Tax setting powers and foreign policy powers included.
It literally proves the Brexit supporters correct.
