Yeah the original statement just annoyed me, that "1E and 3E's FR is more popular than 4E and 5E's FR, therefore adding Dragonborn is bad."
Because one, you can't really prove they are more popular unless you actually commissioned a means-tested poll of D&D players. And two, even if you did, it would be heavily slanted in favor of 5E because it's just way more played than anything else. And if you did somehow find the more popular one, it still may be unrelated to Dragonborn.
I did try playing devil's advocate on my replies, but it's definitely frustrating when people try "proving" the un-provable
