I no longer shoot at any 3D events that are not all trad, so this is not much of an issue anymore. The compound archery clubs in the area closed down a while back due to economic reasons. I got some good natured ribbing from a few of those guys, but nobody ever got snarly. In fact, many of them were interested in my trad gear and jumped at the opportunity to shoot it. Two of these guys bought trad gear specifically from shooting my bow. Generally, I was the only trad shooter there. Trust me, if you shoot reasonably well, amongst the sarcasm sent your way, there will be a grain of respect also.
As for hunting, I am the only one at my hinting camp who is an archer at all. No, I did not really mean hunting camp. We have all gotten so fat and lazy in our old age, that we merely hint at being real hunters over deer camp weekend. I do hunt seriously most of the season, but this weekend is more social than serious; consequently, they do harass me quite a bit about my equipment. Yet, when a couple of the non archers picked up my bow they conceded that it does require a bit of skill to do it.
In short, it does no good to argue about the effectiveness, tradition, or fun with those who criticize our sport. But, if one shows interest, let him shoot your bow - you just may create a convert.
