You bet your ass it's inappropriate. We don't appreciate foreigners like you referring to Avram Iancu, a national hero, as "someone famous for killing a lot of Hungarians. - 

Political bias

I've reverted the last edits to the last version by Bogdangiusca. Obviously POV, using words like "extremely mationalist" and "an affront to the Hungarian community" have no place in an encyclopedia article whose role is to inform readers about said person, nothing more. If you have strong opinions about a politician, write them on your own website. Wikipedia can not be used for:
Praising a politician.
Providing negative propaganda about a politician.
If you want to do those things, it is your right, just not here. It's not up to you to judge whether Funar's municipal modifications were "anti-Hungarian" or whatnot, since I can sure as hell list a whole list of anti-Romanian actions that the UDMR has done in its history. -
