US citizens haven't been brainwashed into thinking that their government is their friend, at least not to the same extent as the EU.
Honestly, if you talk to real people within the EU, you'll find that maybe half of them are mostly against the EU. Real life is not the same as HN, because most citizens are not part of the "elite" that benefits the most from EU programs and systems. Like all governments there are very good things about the EU and very bad things. And somebody has to pay for their maintenance.
You should be concerned if your thought patterns are healthy if you dismiss everybody with a different opinion as yours as "brainwashed". It doesn't help you in the long run.
