I think each side gets worked up by the "extremist" in each side.
I love to trick out my reels, buy expensive rods and have good equipment. I don't have a boat yet, but hope to one day. I feel that the better stuff helps me because I don't consider myself to be that good of an angler. Therefore, the better rods allow me, the less experienced angler to detect things that a MORE experienced angler would probably feel or notice even with cheaper stuff. As I have stated multiple times, there are guys here who could outfish me 20:1 with an ugly stick, mono and a zebco reel against my daiwas and dx's.
What gets guys like me (Those who like expensive stuff) angry is when people speak as if buying expensive gear is a fools errand and a waste of money. That rods over $150 are a scam and catch fisherman yadda yadda yadda. If you don't believe in spending alot of money on a rod or reel, that's fine. However, don't bash those that do as either snobs or fools for how they spend their money. I don't have a wife or kids, I work hard and choose to put my money into gear as opposed to hunting, cars or any other number of hobbies I read about people here.
On the reverse side, those who spend less get angry when they feel they are looked down upon by tackle snobs. There is a certain forum where this is entirely apparent. Terms like "refined", "smooth" and "crisp" get thrown around when speaking of high end rods/reels but not with moderately priced gear. I can see why this would get people upset especially when they are good anglers lol. It also is wrong to imply that only those who use high end gear can catch fish.
Maybe it's because I have used a wide variety of brands and price-points, I find it very hard to bash anyone as I have been there at one point. On one hand I can appreciate the guys who spend a ton on gear I could only dream of having. On the other hand, I can appreciate guys who can catch fish with anything they use. In my mind, it is only when one side bashes the other that I get annoyed as I feel it is entirely unnecessary.
Last comment, conflict also seems to arise from two differing points of view on fishing. One group views catching fish to be the only goal. Lines such as "the goal is to catch fish, bottom line" etc are what I mean. This comes off like a tournament mentality to me, which is fine. Catch fish using whatever you can in any way you can. The other view seems to be the joy of fishing both in the ACT and catching. Namely, the feeling of using a great rod, great reel, great line and the experience associated with it as well as catching fish.
