Because Wizards of the Coast, the owners of D&D have lately quite often brought real world into their fantasy game for marketing purposes, first be their "No race is evil" statement, the changes they do to Orcs and Drow because them being evil is racist and now their "everyone is special" rules changes that basically remove ability scores from races as everyone is free to trade them around, again because apparently the biology determining your strength is racist according to them.
Or, alternatively, enough players are going, "I have in mind a character concept for a race and class, but I don't get any racial bonuses to get to a 16 in that class's favored ability from point buy, and still like to make the character without the rest of the people at my table yelling at me for playing 'suboptimally'."
I got enough flak for saying "I'd like to make a Halfling Wizard" just in a D&D thread on a discussion forum, before even getting to a table.
