A fire snake is whatever the game designers wrote it to be. It has no real world existence.
The designers could have chosen to make it something other than the underage offspring of a sentient race, and you would have been none the wiser.
This is the point you keep deliberately avoiding.
I'm not avoiding it. I've discussed it before.
The burden of proof of a designer creating an "underage offspring of a sentient race" being an unacceptable thing is up to you. You are the one who is bothered by it.
Many of the rest of us are ok with the design. You are the one who doesn't want it.
There could be art drawn on a wall in my neighborhood and everyone in the neighborhood is fine with it except one person who is offended by it. The person offended has to prove to the local authorities that it is in bad taste or an eyesore or whatever, it is not the burden of the people who are ok with it to defend it. You should take your concern to WotC and maybe they won't add it in 6E.
There is nothing about the "story" of salamanders that requires them to have smaller counterparts that are easier to kill. Why include them?
Because they have been in the game system for 30+ years?
A better question is: Since they have been around so long, why NOT include them?
They even have their own wiki entry: Fire Snake
I think you are merely defending an imagined attack on your preferred playstyle.
Nope. I could care less. But when someone comes up with an argument that is based on emotion, I tend to question why.
Your point has nothing to do with the fictional game and everything to do with real world people (such as yourself and D&D girl) having some moral thing in the back of their heads. Really not much different than the people who wanted D&D banned because it had demons and devils in it, but just less intense.
Ok, story time.
Back in about 1984 or so, I was at lunch with a friend, telling him about a FRPG that I had designed. After lunch was over and we were walking out, a woman came up to me and asked "Were you talking about Dungeons and Dragons?". I replied "No, we were talking about a similar game that I designed. But if you'd like to pick up a copy of Dungeons and Dragons, I can tell you where you can get one.". She replied "Did you know that people who play Dungeons and Dragons are devil worshipers?". I replied "Of course, do you want to join our game?". She went white and raced away.
