Ok... so someone check me on this... am I really being a jerk?

Someone posted a picture of a 1902 sight on FB with the caption that read he finally received his 1901 rear sight, and thanking the guy who sold it to him.  I responded saying "Ummmm, that's actually a 1902 rear sight." 

I then got told by the guy who sold it to him an he was restoring his 1898 and installing the "Army Upgraded sight"... and basically called me an azz... asking me if I was the kind of person who likes to "Piss in People's Cheerios!"  The guy also posted a separate comment that he's just trying to help people source parts and people (like me) with "BS Superior Egos should get lost.

I then responded saying that I meant no offense, and that I was just pointing out that it was an 02 sight and not an 01, which are (as we all know) vastly different.  I stated that the Army preferred the 1901 and the NG used the 1902 sight.  I also stated that Krags went through many sight changes and so there really are several "Correct" variations so long as the proper hand guard is used.

Ok... so, am I really being an Azz when I just pointed out a minor fact?  I may have made an assumption that he thought he was looking at a 1901, when in fact it was a 1902 and he may have not known the difference... but did I really come across as offensive?  Maybe I should just have butted out, but most of the guys on the FB Krag page know me, and I really do try to help... not piss in cheerios!
