Oh gosh, the people complaining about this shows inclusiveness sound like "triggered snowflakes". It's a good show, and carries the same spirit as Avatar: The Last Airbender but more lighthearted and not as strong lore-wise.
Both Avatar: The Last Airbender and Legend of Korra were hits. They both featured strong female characters, strong warriors with disabilities (Toph being blind and the most powerful Earthbender in the world), inclusiveness in regards to culture and also LGBT characters.
The Dragon Prince is a good show, if you were to critique it try criticising it over something relevant and not as a reflection on the prejudices you hold in the real world.
