i think the UK should be independent.
You've shown in this very thread that you have no idea what the EU does or how it works. You throw around the word "independent" as if that means anything by itself. You say that the EU has caused complexities with the custom procedures when it is LITERALLY the exact opposite. It's a customs union and you should probably look up what that is.
All you're doing with Brexit is throwing away your right to have a say in the decisions that get made at the EU level. You still will have to abide by most of the EU rules because guess what, that's how globalization works. You cannot simply undo all the complex interlocked connections and systems that have been established since 1973, economic or otherwise, nor is there any good reason to. I wish we could stop pretending that retreating back behind or walls is a position that is in any way, shape or form feasible to tackle all the problems we're currently facing. It isn't.
The Brexit campaign was full of lies and misinformation, that is a fact. At the moment, no one has a fucking clue where this is all headed. That is also a fact. It's been a complete shitshow for the last three years and it isn't going to get better any time soon. You're not going to get a better deal and it seems unlikely that the current one is ever going to pass parliament. If you leave without a deal, it's going to fuck up your economy real bad to say the least. Your best bet is to try and forget this whole thing ever happened instead of clinging to the notion of "leave means leave" because you don't understand how anything functions.
Oh and by the way, there are a bunch of studies that support the connection between the decision to vote Brexit and racist sentiments, regardless of how many "racist bones" you have in your body or not. Enjoy your independence I guess.
