1. Just like the police officer who pretended he was a SEAL, he inadvertently hurt the PD and made the whole police force look bad. Wearing tridents around and pretending he was a SEAL not only blew up in his face but also in the face of the courts, and his credibility.
What does this have to do with airsoft? Lots! Who do you think would find the most enjoyment in this sport? Gun owners. Who do you think could back this sport up the most? Gun owners. Who takes more flack and more grief over issues created by idiots with airsoft guns? Gun owners..... Your second base of people are probably going to be military/ex-military/people supporting military. Same issues.
2. When we shrug and ignore the situation two things happen. First if we don't police ourselves some idiots in the GOV will figure we are a threat to society, or promote aggressive tendencies in everyone.

You may disagree but I can point out that Cali will probably be the first to start this crap. What does this have to do with fakes?
Breaking News: Former Navy SEAL trains kids to shoot then lets them loose on school How about SEAL goes berserk on airsoft field, or god forbid "Man claiming to be SEAL shoots innocent civilian he thought was a threat" Eventually this will happen as we have seen enough of this kind of crap for real but what the internet has done is given every person doing a story, the ability to Google someone in 5 seconds. When they do they don't look hard, and use the word alleged (which is ignored) in front of SEAL to cover there butt. Weeks later we find out he was a poser wack job and another strike against Airsoft in the papers, and the retraction on page 12 is ignored by all but the community.
First we can condemn the hell out of these guys, and make pariahs out of them in our own community. That should give the community more credibility by the people we would have the most fun shooting at and having fun. John Wu and others have promoted the combination of soldiers into this sport for the fun cool factor, but most Mil and LE scoff at airsoft because of the bad press alone. If we don't promote ourselves and good clean fun, honest, straight forward, then anyone who takes a glance will see this....
Headline: A bunch of fake Navy SEAL, Delta, Operators are out again on a field pretending they are as cool as the characters from COD4.... again.If you dont see that as a issue maybe the airsoft community needs to get smacked around a bit and woken up to the fact.
As for the DD214 comment, if you are smart enough to bring that up then you are smart enough to spot a fake, and bring it to people like the POW net, etc. To many of us are soldiers, gun owners, and enthusiasts not to realize this crap may sink our ship in the end. I would like to see us get up and prosper.
