Because:
>Part of the appeal of furry races is seeing how they interact with humans
>Most people are at least partially furries themselves (the amount of people who don't like any anthropomorphic animal characters at all is very small, seriously how many people hate Mickey Mouse or Donald Duck?)
>The furries already made a few games of their own but D&D continues to be the most popular game and it has furry races available
>Most people who get angry about furries are doing so to cover up something way worse about themselves
