I hate to drag stuff up from a while ago, but...
In what world are centaur and bird people 'wacko' species? They're stock fantasy and absolutely generic enough that you'll see games changing them up to give their own spin on both, same they do with elves and dwarves. D&D has weirdo races like absolute mainstays the Gith, but centaurs and birdfolks aren't them.
Regardless though, to the original question, yeah, I'd play other stuff. I told my friend about D&D and her first questions were "can i be khajiit", not caring about mechanics and showing that the aesthetic of being a sneaky cat person was what mattered. Aesthetic is absolutely something folks will care about and I'm surprised it hasn't gotten much saying in this thread. Mechanics matter, lore matters, but aesthetic absolutely also matters. That drawing of 'what is this thing' absolutely is going to affect people's perceptions of what to play and, even divorced from mechanics, if you present a neat enough picture of a different option? Folks will go and play it
