Earlier quoted context omitted.
Serb here, not sure why would anyone "mix up" macedonians and serbs in any context, and why is a bigger differentiation necessary. Even in the bloodiest years on the Balkans, the relations were very reasonable. Today in Serbia, even the most nationalistic groups (of any kind of influence), don't take Northern Macedonia in discussion. The relations between Bulgaria and Macedonia were a bit more bumpy, I don't know all…
It's maybe important to note that these disputes (and possible disputes) with Bulgaria, Greece and maybe(?) Serbia have almost none impact whatsoever on the daily lives of anyone in the region there. No animosity, no nothing basically apart from politically organised rallies here and there. Situation with albanians on the other hand... is interesting.
The situation with Albanians in Macedonia is disconcerting, at least from a Serb's perspective. It is just too easy to notice a pattern of behaviour, incidents and evenrs, and almost threatening stance, even in some comments here regarding the Albanian majority in Macedonia. Serbia has been through that and handled it poorly, and I'm afraid that Norhtern Macedonia is on the same slippery slope.
