And now we see yet another example of you not reading the post. Maybe I need to say it clearer for you. I. Never. Said. That. The. Term. Is. Inaccurate. When. Used. In. The. Correct. Manner. That is not something I commented on. Can I expect an actual reply this time or more rubbish that talks past me?
I have been drawing parallels between what I said, what you said, and how they interact.
You used an example involving someone using the term "white knight" in the incorrect manner while in another paragraph also alluding to how someone could not discern another's motive on the internet.
When the term white knight is used correctly - the correct term that is used on the internet being used most frequently during the MMO boom before the release of Burning Crusade for World of Warcraft - it is used because the motives of the white knight have been discerned due to their actions. The example I gave of this situation included the phrase
when the individual has no actual argument other than "stop being so mean" to defend the ire the defended has earned
this scenario allows motive to be easily assessed. It doesn't REQUIRE a desire for sexual reward - just that it OFTEN does. What remains true is someone leaping to the defense of another when the individual deserves no such defense, often due to the individual's actions immediately prior. The white knight and the defended could be friends before hand, but it doesn't change the fact the defended is being defended for unrelated reasons to what they are receiving ire for.
When ALL of those criteria are met the use of the "white knight" term becomes accurate and is the correct use.
Motivation over the internet can be discerned. Those who use the term white knight in the correct manner usually have the sense to only use it when motive has been shown to be discerned in some way or at least there is evidence that meets the criteria to call someone a white knight. While difficult it is not impossible and various people have motives that are more easy to discern than others. When people toss out the term "white knight" in almost any conflicting situation then of course they will likely be inaccurate with their assessment of another's motive. When you apply something to everything it's going to be inaccurate most of the time.
This is related to what you said
You get called a white knight if the one calling it doesn't like your argument, that simple
because it covers the scenario you introduced of someone calling another a white knight simply because the argument being presented conflicted with the accuser's. This is not the case because it isn't "that simple" because it is not always used in that manner. It also links to the idea you raised that motive is very difficult to discern with accuracy over the internet.
