The problem here, Russ, is not racism - it's sheer confusion!
The European Convention on Human Rights is an international treaty which has been signed by 47 countries, including quite a few (e.g. Russia) which are unlikely ever to be members of the EU.
Above all, it has nothing whatsoever to do with the EU. If we were to leave the EU, it would not affect our membership of the ECHR in any way, and it is inconceivable, IMHO, that we would cease to be members for any other reason.
So it's just irrelevant.
As I said before, Russ - you're in a hole, so stop digging!
