Not really. If all settings are kitchen sink settings, their leaves very little room for creativity. Tolkien doesn't have dragonborn wandering around.
It's fine to only enjoy one type of setting, but calling anybody who prefers stronger narrative themes in their settings a bad DM is deeply unfair.
Fully backing mestewart's post ("I hate X so you can't have it" =/= "prefers stronger narrative themes"), but thought I'd add a little bit myself: You make it sound as though the debate is between "any amount of restriction whatsoever, for any reason, ever" and "never ever restrict anything at all because all options are present and well-known always." That's not the kind of discussion I've seen, here or elsewhere, when this topic is broached.
The way most people actually speak about it is exactly the reverse: every single universe is,
and should be Tolkienesque, unless you give a fantastically good explanation for why it's not. Which is just as bad. If all settings are Tolkienesque settings, it leaves very little room for creativity. Skyrim doesn't have dwarves wandering around.
Edit:
And moreover, your presentation simply continues the exact same ghetto-izing concept that I complained about earlier, albeit with different words. Liking dragonborn does not, even in the least, entail liking "kitchen sink" settings. Neither more nor less than liking dwarves, tieflings, elves, cat-people, halflings, space goats, or any other concept you can name. If we're going to talk about unfairness of arguments, it cuts both ways:
liking things with less history or tradition doesn't mean I like absolute kitchen sinks. Because I don't. Most "absolute" kitchen sink settings (100% of everything is present and well-known everywhere in it) are incredibly boring, because they
do bland-ify everything.
Of course, I also think that the rampant overuse of Tolkienesque concepts (elves and dwarves in particular) has bland-ified them, too, but that's far more open to debate than the above.
