Technically, they can be binding, but this one wasn't. <pedantry/>
Actually interested in pedantry: it actually can be binding in the UK? Of course referendums in general can be binding and in many other countries they are, but I thought it was not the case of the UK.
As far as I understand in most US states there are actually already data breach laws which require companies to notify users if their data is known or believed to be breached, with delayed notification allowed only if law enforcement requires it to facilitate the investigation.
The most common age for "sex offenders" is 14 years old: still dangerous decades after the fact? Really? On top of that most "sex offenders" would not even be labelled as such at all in most of the civilized world. Furthermore sex offenders have actually a pretty low recidivism rate. The whole crackdown on "sex offenders" is misguided and driven by irrational overreactions and the whole concept should be reviewed and drastically reformed.
In general, deciding if and when somebody is or still is a risk to others is actually pretty hard: you only think it's not hard because you believe in a solution which is "clear, simple and wrong".
Exactly: what people fail to understand is that by making referendums much more difficult to be successful they would actually place even more power in the government and reduce their own power to affect it. These kinds of decisions are very dangerous since once the government gets more power it's very difficult that it will renounce it and it's the kind of decisions which will soon or later bite back
So what supermajority was required for the UK to join the EC back in the 70s?
None, but no majority requires leaving the EU today either. In any case the whole debate of a popular vote being required to join the EU in the first place is a huge can of worm by itself.
Ok. If you impose a very high supermajority to one side, you've effectively already chosen for everyone. The vote becomes farcical. Why should people participate in meaningless pretend elections?
The side getting the supermajority is the status quo. I don't like it much, but the idea of requiring a higher majority or a quorum to change the status quo makes sense on paper, but then you have governments like Italy which plan bothersome referendums at super-impractical dates to try to deter participation and basically try to "win by default"...
This isn't fucking rocket science. It's basic fucking Parliamentary democracy of the sort that the UK is supposed to deliver.
The point of referendums is exactly to get the parliament straight when it's not doing what the people wants.
We don't know one millionth of one percent about anything.
