Brexit has definitely changed my mind on one thing - majority vote in a referendum is bad. Or rather, the percentage vote required should be proportional to the gravity of the question.

A referendum should be held on major political stuff (like leaving the EU or Scotland leaving the UK) if national polls have pinged the opinion at least 60%, and then it should also require a higher majority (like 60%) to change. This ensures a big major change happens if it's really wanted, but for very divisive issues it will take time.

And it should require more than 60% otherwise if you go 50% like now, you have half the country hating the other half. If we kept the status quo, then the brexit people would have had to keep up and slowly change peoples opinion so the majority of the country agree.
