As a state, idk, I'll go mad If I'd had to live in Russia. I don't like how everything is organized.
I personally dislike the soviet like mentality; gopnik way of speaking / behaviour as well.
Attitude is decent, no bad feelings towards Russian speaking Estonians from Estonian speaking ones. Although, some negativity might be seen towards regular Russians as they may carry some of those characteristics I mentioned before.
TL;DR Behave well, be a decent human being, learn and try to use the language and you gonna be good.
