It’s kind of an arbitrary starting point, since ultimately every anti-RDF talking point is illogical and/or delivered in bad faith, and needs to be addressed, but hey you gotta start somewhere and this one applies to more than just the RDF discussion.
Point being, it is very frequently implied or outright stated that people who reject tedium are being lazy. Of course, that is not at all true. Laziness is defined by a general lack of ambition rather than a lack of desire to do or participate in specific activities. Not wanting to engage in the contrived and non-productive tedium associated with using analog LFG tools does not make someone lazy so much as it means they have self-respect. Someone willing to, as the talking point goes, spend all day queueing for and running dungeons, is by definition not lazy. If they are willing to do that, but not spend the same amount of time with a much larger percentage of it spent cosplaying a chat parsing bot, it’s probably for the same reason that they would spend all day running dungeons, but not all day running dungeons if they had to put a toothpick under their toenail and kick a wall between each run.
