I don't think it amounts to that. But do me a favor. Imagine a hypothetical class that you don't think belongs in the game. It could be the Evil Stepmother, the Space Marine, or something else -- it doesn't matter what it is, as long as you would exclude it from most of your games and wouldn't even want to see it as a player.
Now imagine having to tell your players that they can't play that class.
Imagine your players asking why, and having to explain. Imagine having to do this every now and then because it'll come up more often than you think.
Imagine looking for a game to join on Roll20, and seeing that a lot of games include that class.
Imagine the class turning up in a lot of official adventures and having to write them out.
That's how I, and many others, feel about the warlord. It doesn't belong in the game. Its inclusion negatively impacts us. It's just one more thing on the "not-fun" scale of D&D, which, if it tips too far, makes us not want to play anymore. So while you're unhappy that the warlord isn't included in the game, remember that a lot of us would be just as unhappy if it were. There's no way to please everybody here. And no one is persecuting anyone else. By arguing for the warlord's inclusion, you are arguing against our happiness just as much as we are arguing against yours.
