My gut instinct tells me it was a bit of this as well (note, No back reading; this is just my gut instinct/first impression):
Neon dislikes SJWs for nebulous and hard to define (nonspecific, but deeply felt) reasons.
Descan leans SJW; wants specific things he can use to argue against, as he dislikes general anti-sjw sentiments and feels he can 'win'.
Neon does not have specific reasons for his dislike of SJWs, but attempts to give some examples.
Descan thrashes the strawmen, declares them such.
Neon reiterates that he does not have specifics.
People get confused.
Situation deteriorates.
That is very much in line with the "If people are responding with [emotionality] instead of dispassionate criticism" I was meaning, and if true, I am indeed displeased.
Remember, you dont actually NEED a specific reason to dislike something, much like you dont need a specific reason to like something. It is a personal preference, and choice based on said preference. EG, if I say I dislike asparagus, the reason I have for disliking it (It has that GROSS 'raw sweet-pea' like taste, like raw peas, and raw peanuts. GROSS!), can be a reason somebody else does like it. Ultimately, it comes down to "It has X, and I dont like X", where there is no real reason for disliking X, other than experiencing a negative mental state when experiencing X. Somebody else chiming in in dismay that "YOU DONT LIKE X!!?? I LOVE X! HOW CAN YOU DISLIKE X!!??" is not helpful, and forces the person who simply has a negative mental state concerning X for reasons not even they really know into the defensive. (Due to the innately subjective nature of the matter concerning preferences and likes/dislikes, the exact opposite scenario is also possible, where person-A states they love X, and person B demands to know how they can love something nasty like X, and wants specifics.) That some things are essentially qualia, in terms of like or dislike, is often something overlooked, and not given proper dispassionate evaluation.
It applies to food preference just as much as preference for company and choice of discussion topic, as it does to things like SJWism.
Basically, Neon does not NEED to justify his dislike for SJWs, and anything derived from that line of thinking is logically unsound.
I am displeased that instead of approaching this with a lack of passion either for or against, it appears that our members have instead decided to join sides, rather than dissect the actual situation, and determine it as being absurd to argue about, using pure reason.
