That's the worst kind of straw-man... You are declaring that it's used in a general way, and then shooting down the generalizations that you've created.
You may as well be saying "the problem with feminism is that not all women have every been discriminated against, it's just all based on a useless generalization and so it doesn't exist". You're very stubbornly putting up a mental wall here.
I'm not sure you're reading what I wrote. As a core idea privilege is one lens through which to view the world. It is faulty, and the ideology that generates it leads to omission of those faults and undermines the very end goal (equality) it purports to strive for.
Is it possible that you misunderstood my view on inequity. I think when some hear pushback to the idea of privilege they assume by default the critic is maintaining that inequality does not exist. If so, please understand that this is NOT my position.
Then you can calm down with the circlejerking.
This response is concerning. What do you mean by it?
The second point refers to the "anti SJW-esqe" nature of a bunch of recent posts here.
In my experience with groups of these people on the internet, they follow the same pattern as most fear-based groups: take a sliver of truth - there are a small number of people who happen to share an extreme view - blow it up into a big bogey monster - these people are a mass movement that's ruiining my country / attacking my culture / influencing society, rant about them and tear down their position (which is easy as their position is extreme, but also futile, as all of your attacks are actually straw-man arguments due to the initial assumption that this boogy man even exists).
Both the initial extremist group, and the counter-group spawned by their beliefs are small and irrelevant, but seem big to themselves and each other due to them living inside echo chambers and circlejerking themselves into self-reassurance that their imagined foes are indeed worth obsessing over.
The SJW/anti-SJW echo chambers are unfortunately familiar with a lot of gamedev people these days, thanks to the whole #gamergate thing... which btw is kind of a banned topic here now due to how controversial it is.
In my experience and opinion, it's not necessary to debate that taboo subject anyway, as both sides of it are actually much smaller than they think they are, more extreme than they think they are, and more irrelevant than they could imagine... so when the terms came up in this thread it made me immediately wary of stepping into the echo chamber of hate.
As for your views on privilege -- you're consistently talking about an ideology, a philosophy, a lens... which is fine, but I don't believe in it. Not that I don't think it's right or wrong, but that your entire view on the subject is orthogonal - a boogeyman to me that I don't have to believe in.
I'm sure there's some tiny minority somewhere that does believe in this ideology that you're tearing down -- but to me, that's not what the word means, and this minority doesn't even show up on my radar except as a caricature.
The concept of privilege is much greater than this one caricature that you're focused on. Within that concept, as with any concept backed by a common word, there's a near endless set of meanings. Within those meanings, there is the small sub-section of "Privilege theory", which mostly fits the thing that you're deriding... However, this just happens to be an academic model that provides a context for social analysis. As a sociologist, you can use that tool when appropriate, and use other models when appropriate. You can also use it quite sensibly, for example, a recent study on non-conscious racism here found that people with foreign-sounding names are less likely to be granted an opportunity to inspect a rental property outside of the advertised inspection times, while people with "normal" sounding names were more likely to be given that favor. That's a completely boring normal bit of psychological research into how people function, which happens to be well described within the context of privilege theory - not something that requires the researchers involved to become indoctrinated into a narrow and inadequate world-view. Sure - the responses to the research could be extreme, or sensible, but that's irrelevant to the work itself.
Just because some minority has their own weird little internet subculture that's abusing the word, that doesn't mean that I've got to put on academic blinkers myself. I can just choose to let them do their thing without me.
So what you're actually ranting against is people who are not academics who have adopted certain sociological frameworks into their vocabulary without having the required understanding of, training or even desire for rational thought required to be able to make proper use of this tool within their daily interactions with strangers on Tumblr.
I deal with this problem by not having a Tumblr account - not by attempting to tear down the ideas that they've misappropriated and perverted.
