Politically it can go either way. Overall, airsoft seems to have no influence left or right, pro or anti, although most of the players with really high-end stuff and the collectors tend to be more pro gun, and also are much more likely to know a bit about real firearms.
There are a lot of different kinds of people in the game. Here's a short list:
1337 H4XX0Rz: These guys think that they are all that, and typically have an unhealthy obsession with Multicam. They fail to recognize that they are playing a game and they are likely to call themselves "Delta Seven" or something to that effect. Often, 1337 H4XX0Rz will spout firearms and gear knowledge which makes little or no sense, or repeat common myths about the reliability of the M16. They are not sure why the XM8 isn't in service yet. Interestingly, 1337 H4XX0Rz are often taken out by one guy in a 30 round magazine's worth of fire, as they have a tendency to bunch up in the middle of the woods while trying to look tactical.
Gamers: Gamers are just there to play the game. They chose airsoft rather than paintball for cost reasons, with realistic guns as a bonus, and hence tend to use lower-end airsoft guns. Gamers are rarely braggarts and far more tolerable than 1337 H4XX0Rz, and their ultra-casual view of the game supports this. However, gamers are also less likely to have knowledge of real guns, and can be apologetic about their hobby - they may say that they are against real guns, so that they are not criticized as much by non-airsofters. Additionally, some gamers exercise poor safety with their guns, as they don't see this as picking up a bad habit.
Chairsofters: This term is sometimes used to describe someone who does not play airsoft, but sits at their computer wishing they could. More commonly, though, it is shorthand for an airsoft collector. Some live in countries where firearms are banned - Japan, China, and the UK being notables - others simply choose airsoft for its low cost and ease of use, as ammunition is sub-1-cent per BB and the guns can often be fired even in an apartment or suburban house without causing damage or disturbance. Chairsofters are the most likely to have extensive knowledge of firearms, and many spend hundreds, even thousands, constructing detailed pistol replicas from custom and aftermarket aluminum parts. Many, especially those who use airsoft because of their country's laws, are strongly pro-gun. Some can be a little odd, as people very devoted to their hobbies often are, but they are agreeable people and not the jackasses that 1337 H4XX0Rz are.
Impressionist: I'm adapting this term to describe these people since I can't think of one better. These are best described as reenactors who accidentally stumbled into an airsoft game. They're very interested in military history and play wearing authentic kit to form an 'impression' of a particular kind of soldier in a particular kind of country at a particular time - for example, a Soviet VDV paratrooper in Afghanistan in 1988. Attention to detail is key as these players try to obtain all gear that would be worn at the time, some even going so far as to create weathering effects on their otherwise pristine gear and guns. Occasionally, someone seeking an unusual impression will build an obscure gun themselves - this is often done using external parts from a firearm parts kit and the internal mechanism from a common airsoft gun. In airsoft terms, Impressionists are about 70% chairsofter, 30% 1337 H4XX0R, but it's best to think of them like renactors who use airsoft as their venue and want to have a little more fun by shooting actual projectiles. Nice guys and they do know their stuff when it comes to firearms, gear, and military history, but sometimes they can be a little overbearing.
Skirmishers: Although this word is used in airsoft to describe anyone who regularly 'skirmishes', that is, plays airsoft, I use it here to denote the typical airsoft player. Think of a skirmisher as the average of the four categories above - he/she plays for fun, but likes a realistic gun and a little bit of 'cool guy gear'. Knows a little about firearms, much more than the normal person but still likely to harbor some common misconceptions, and may be pro or anti gun. Can be jerks or great people, but all agree on the importance of calling hits honestly and having a good time whether your thing is realism or pure shoot-em-up fun.
Dumbass kid: This is the 9-year-old whose parents bought him an el cheapo springer pistol from Wal-Mart. He's the guy you see pointing a real-looking gun at you as you drive pass. He's also the wannabe gangsta who has a Glock gat, yo, and brings it to school to show his homies. It's important to note that, to a certain point, it isn't the age that matters. Dumbass kid could be 8, 14, or 26 years old - it doesn't matter - whereas I have known some really good, knowledgeable airsofters who were 13 or 14 years old. It's the attitude.
I think you'd all find that if you really look, airsofters are great guys. Problem is, and this is true for so many things, that the ones you see, the ones who like to be loud and make themselves public, are Dumbass kid and 1337 H4XX0R.
