I guess the reason it comes off as rude is because it is so short and - for my lack of a better word - rubberstampy. It is as if some people don't have time to ask politely for sources. I also think it might trigger the "passive agressive"-detector for some people here. (I think that description has been overused a lot though and don't want to classify it as such.) This might not be your intention but I wouldn't be very sad to see those words less often here. And one more thing: using wikipedia as an example for how to behave in society might not be a good idea IMO.
