... so much for why (see my first post upthread) I generally think that the term "privilege" to describe something demonstrably real and harmful is not a helpful choice.
Again, "having X privilege" doesn't actually mean the same as "being privileged".
"Having X privilege", basically, boils down to "even if you happen to be the most underprivileged person on the planet - X probably has nothing to do with it". And, usually this is because - on a class level, which says nothing at all about particular individuals - people who have/are X tend to do better than people who don't/aren't, all other things being equal.
So, yes, white working class men have white privilege. And male privilege, for that matter, being men. Nothing about this says that they can't, on the whole, still be desperately underprivileged. They obviously can. It's just that this is not because they're white or because they're male but despite. The because in these cases, can pretty uncontroversially be tied to socioeconomic factors.
And, no, having X privilege doesn't make you racist/sexist/homobhobic/anti-non-X by default. It does, arguably, make it a bit harder for you to see how being non-X affects other people's lives and how things you find perfectly normal put others at a disadvantage.
Again, "X privilege" basically boils down to "not having to give too much thought to havibg/being X outside some very specific situations".
For example, I personally never realised how easy post 9/11 air travel was for people with WASP-y sounding names like mine until I travelled to Israel for work with a colleague who had a decidedly Arabic sounding first name and got to "enjoy" the full security risk treatment on account of having been on the same flight booking.
Does this make me personally responsible for the plight of every completely innocent person who regularly gets strip searched at airports? No, of course not! Is it morally reprehensible for me to be called "Jane Bloggs" and should I change my name to "Huda Al-Masri" by deed poll for ethical reasons? Don't be silly! But also: yes, having witnessed this does mean I should recognise that there are things which are not quite as easy for my colleague as they are for me - despite us both being in the same, well paid profession and both, on the whole, privileged. And maybe, just maybe, if I get the opportunity, it would be the kind and decent thing for me to try and help change things in such a way that the Ahmeds and Samiras of this world have as easy a time attending an industry conference as the Nigels and Sarahs.
