Once again for the umpteenth time I am never upset by people's preferences. Those Warlord threads did not just feature people discussing their preferences. They also featured bizarre psychoanalysis of how even liking to play that archetype meant you wanted to boss around your fellow players and absurd shouting wounds back on takes in a game where you recover all hit points sleeping overnight. It's not just I don't like it. It's this thing is bad, and you should feel bad for liking it (and in the case of the Warlord it might even mean you are a bad person).
This is the strong throughline of a lot of online 4e criticism. It never stops at the game. It instead puts those who enjoy/enjoyed the game in the crossfire by assuming they don't care about things like coherency, game lore (which many 4e fans care about deeply) and even roleplaying. In particular this bizarre caricature of a 4e fan as only caring about tactical combat when for many of us a big part of what we like about the game was wanting to have the game work with less combat and having binding mechanics for stuff besides fighting.
