>It's free movement of labour between EU member states.
That distinction is kind of meaningless when thousands of people can enter several EU member states pretty much unregulated, then disappear under the radar and go anywhere within the EU.
GnuGo is easy enough for beginners I think. I also used a bot called Aya when learning, but I don't know if that is available for OSX.
Regarding clients, there are a few options. CGoban2 is the only client you can use to access KGS, which is currently the biggest English-speaking server. You can also try online-go.com which is entirely browser-based so you don't need a client, and there's also IGS, a Japanese server which can be accessed through their own client called GoPanda2 or other clients like qGo2. There are also two servers called Tygem and WBaduk which are mostly Korean. They have proprietary clients you can run through Wine. I think they're supposed to be accessible through qGo2 as well, but I haven't been able to play through it, only observe others' games.
>poor at matching me with beginners of similar experience
I don't know what server(s) you tried, but unfortunately quite a few of them have a sandbagger problem at the lower ranks. Also the ranking system itself has its inconveniences. The difference between a 19 kyu and a 16 kyu might be nearly negligible, but the difference between a 3 kyu and a 1 kyu is usually not. Coupled with the fact that it takes servers a few games to get an accurate rank, it often makes for a frustrating experience for beginners.
I've been playing on and off for a few years. I got to around 1 dan, and hit a wall because I need to actually study regularly in order to improve now, but I'm too lazy. I've been taking a break and planning on creating some sort of routine for doing tsumego every day and pro game reviews.
I've always loved the way it becomes so complex through such seemingly minimal and simple rules (although superko rule and komi aren't particularly simple rules).
That's akin to saying we non-murderers aren't responsible for fixing murders, only murderers are. Anyone can help fix this. You're right that ultimately it comes down to men's attitude and actions but anyone can help achieve the changes necessary.
