Just to extend my earlier point. If people simply argued that they didn't like dragon boobs and they thought they were stupid, that would be fine. WOTC would be in the position of knowing whichever way it went, it was going to make someone annoyed, so, do a bit of market research and go with the group that's going to give you the most money. Maybe that means no dragonboobs, maybe it means dragonboobs. Whatever.
But, the argument never stops there. Sure, @
Elf Witch has made her preferences perfectly clear. No problem. But then there's the next step in the argument. "I don't like dragon boobs because they are unrealistic and thus bad and anyone who likes them just doesn't understand science/realism". They're trying to justify their preference by making it sound like it's an objective issue - it's totally unrealistic for reptiles to have boobs, so, let's go with realism. it's more believable.
Of course, that argument ignores the fact that Dragonborn are a created race, specifically called out in the race lore, and made to model humanoids - which do have boobs. IOW, the presence of dragonboobs is actually justified by the background of the race.
Which then leads to the next level in the argument. Since arguing science doesn't work (mostly because it's a very uphill climb to argue that a magical race created by another magical race should follow science) critics then break out the "sexist" argument. It's prurient to add boobs to dragon born. Never minding actually looking at the images in question to learn whether or not the pictures actually are exploitive - are we talking about boob windows in the armour? Chainmail bikinis? Overtly sexualised images worthy of a Marvel comic book? No, we don't actually see any specific examples. Adding boobs is sexist because, well, making a creature look easily identifiably female is apparently sexist.
So, instead of the issue simply being one of preference, in which case, the conversation is largely over, we see critics constantly beating these two drums in order to force their preferences on everyone else.
