It is because they simply don't know about the history. They see a big screaming piece of metal ripping through the air and sowing death and destruction to everything in its path and that is exciting. A lot of these guys are coming from backgrounds that are non military, and are really just becoming really interested in aviation. They know the very basic facts and that is about it. The good thing is that they are learning and that is of key importance to our hobby. I too get kind of frustrated sometimes (like when people say the blurry LN Tomcat photo is something other than a Tomcat, or a Bis is pretty much the same as a PFM). This being an internet forum... well... it comes with the territory so the goal is to educate and help them learn the history. There will always be knuckleheads out there who don't want to learn but there are fewer of them than there are of the people who truly want to learn and understand. Nobody knows everything but most are willing to learn and that is very good for our community.
