Airsoft is nothing like reenacting, END OF STORY. Hate to ruin your fun, but there it is. Nothing good can come from us trying to call ourselves reenactors. For one, it will greatly offend real reenactors and history buffs, making our sport even further of an outcast sport within the military enthusiast community. And if a reporter ever looked up the deffinition of reenacting, do you think they'd paint us in a positive light? Hell no. They'd potray us badly, as people with something to hide, as people who can only get away with playing our sport by trying to pass ourselves off as reenactors. The bottom line is, because of the nature of our sport, we can never be truthfully called reenactors. Period. Argue all you want but thats the truth.
Read the deffinition of reenacting if you dont believe me. Then tell me how airsoft could possibly be considered that.

Now, you want to change the name of the sport and become more pc, more public friendly, great. But not to reenacting.
Modern Military Simulation would work fine. It'd achive the same goals without the risk of pissing people off.
