UK Participated in lawmaking until they where basically kicked out, they voted on stuff that was very hated by the population In the remaining EU countrys, they Made lots of propaganda against Germany, France and EU itself, fueling the whole Hungary and Poland Desaster, they fuck over the whole fishing thing, the science fuck up, the whole shit with Ireland (basically gambling to bring the IRA back...) and being completely unbearable assholes since then.

Also, Climate change, Environmental protection Animal rights...

Basically, your government left EU to get closer to a shithole semi dictatorship, or at least thats what it looks from outside...
