Groupthink.
Firearms enthusiasts, hunters and shooters down at the local gun shop or, most especially, on the internet seem to enjoy portraying themselves as mostly subscribing to the same notions. Or at least, most will pretend that their opinions align with the majority's. We do pretend that there are many gun-related concepts that are so true, we take them for granted and are shocked when someone "violates" our beliefs.
We like to think we have a code. We like to believe there are things you just don't do.
Some truly believe in all seriousness that it's sacrilege to put a scope on a classic lever-action .30-30. Many here believe that the S&W K-frame is the pinnacle of revolver evolution. Start a thread on egregious, unsafe gun-handling and immediately everyone chimes in, absolutely horrified that there are gun-owners who seemingly cannot comprehend The Four Rules. Try making a disparaging remark about Col. Cooper on a 1911 forum. Admit to a negligent discharge and 75 guys on five pages of posts will righteously proclaim they've never had an ND, nor will they ever... Denigrate the venerable 1911 and get out the popcorn. Us old guys that like our guns in blued steel and American walnut know way more about stuff than some skinny jeans-wearing, man-bunned millenial who came up on black plastic guns.
We all subscribe to the Internet Code of Firearms Enthusiasts and Shooters. Which takes some time to learn. We take our lumps while we learn to think like we're supposed to. We excoriate the newcomers when they step out of line, but mostly, those who challenge our code. Often, we as a community tend to be judgmental one-uppers. Even though we are all still rugged individualists and pretend we don't care what everyone else thinks...
I agree. Me too.
Personally, I think front cocking serrations and rails on 1911s (which should be chambered only in .45 ACP, obviously) are the spawn of the devil, and if you don't agree with me, I will publicly humiliate you down at the gun shop or out at the range or on the internet...
