Maybe they're getting voted down because the ECHR hasn't got anything to do with the EU.

Everybody’s pointless political comments get downvoted. When I make a dad joke about Trump, it always ends up with -2 karma. (Still I come back eventually because something about that orange real estate baron just shuts off people’s better instincts.)

Constructive comments about the EU’s failings seem to often hover near the top. It’s all in how you present your negative opinion.
