I do not see the problem. For a while I replaced the clan leader Kozak (Russian clan), and in our team had a few Poles and at least one of them was a Polish nationalist. Also, in our clan were Russian nationalists.
We had a very interesting talk and we had no problems in communicating with the exception of the language barrier - not everyone in our clan knew English.
For all the time that I played in the DLG, there has been only a few minor incidents of abuse to me and as I recall, it was not due to the fact that I am Russian. In any case, even if the situation has changed for the worse, it makes no difference to me and even more so, I would not make those topic on the forum. I just laugh at those idiots who try to insult people on the Internet.
By the way, hatred of other nations in general is not a sign of nationalism, it is just chauvinism.
I used the google translator, sorry for the mistakes and omissions.
