May be a tad opinionated...
https://en.wikipedia.org/wiki/European_Convention_on_Human_Rights - "...the convention entered into force on 3 September 1953. All Council of Europe member states are party to the Convention..."
The EU was formed in ~1993. The Maastricht treaty, and all that subsequent jazz - If you remember the fuss over it at the time. So, only those treaties and such after 1993, or those superseded by EU rulings are potentially going to get a full kerb stomping and kicking if we go full article #50. This is only conjecture from a poor semi-edumacated lad (thank you Labour, Tories. A pox on _all_ your houses), but I suspect the shape of the future to be somewhat familiar and not utterly alien. Human nature and history being what they are (rare bright spots in a whole load of crap.)
I'm disappointed that we may be leaving the EU. Note: not sad, weepy nor panicky Kermit the frog arm wavy. The dissembling, rhetoric and overtly emotional appeals to illogic are prime fuel for the dysfunctional who just love having an enemy, any enemy to fill up on hate with. Politics and soap opera indivisible.
This needs to stop or we'll continue to tear ourselves apart. I loath the GWB with us or against us partisan mentality that seems to wash over politics today. We need to get real and work it out, think instead of blamestorming the other side. Calling brexiters names will only push them Trumpwards. What happens if you get called a bad name? You think better of the name caller? Love em' up more, right? Use your noodle and persuade. Be subtle instead of deionising putdowns.
OK, time for my meds and a cold shower. Nurse!
 Demonising of course, but I let the spell checker have its way.
