There's a well-known, yet little understood phenomenon that overtakes newbies in various areas of animal husbandry. When given some advice, geared for first-time keepers to facilitate easy success in their new endeavor, they come to believe that certain guidelines were actually well-defined and irreproachable "rules", and take it upon themselves to judge every shop, keeper, or breeder they come into contact with based on these perceived "rules".
Luckily, over time, most will get over it and learn (through research and experience) that the guidelines handed to them were very general methods for preventing their avarice from leading to certain failure. Yet, in the meantime, they seem to fall into this trap with little understanding of how it makes them appear...
The new dog owner is aghast when a white highland terrier is pulled out from a vermin's hole by its tail (it's designed for it!).
The new snake keeper becomes indignant when seeing a rack of "sweater/blanket boxes" used to house boas/pythons/corn snakes (vertical space is useless to a snake, who prefers horizontal space and actually finds comfort in small areas...hence their habit of sleeping in gopher holes and termite mounds).
New fishkeepers are ready to call the ASPCA when they see 1/2-gallon containers used (that's all a betta needs).
Unfortunately, as I've been involved in all three of the above examples of animal keeping for quite some time, I know this "syndrome" all too well.
For many of us, the response is pretty basic.
But sometimes, it's downright offensive! If what you learned in the first 6 months of animal husbandry was all there is to know, then the people that the newcomer loves to judge smugly wouldn't still be interested after decades of passionate involvement. When that newcomer bores and moves on to something new, the rest of us will still be plugging away with our hearts and minds content in the knowledge that we're still getting better and better at this gig, chuckling to each other as the new batch of fresh keepers comes by with the "holier than thou" arrogance of one who finally kept their animal alive for more than a month.
But, maybe...just MAYBE, they'll learn! 8)
