Sorry, but male - especially white male - privileged does exist. It's the part where we can go to a job interview and not thing "am I going to not get this job because of my gender or skin colour?" It's the part where we go through customs and don't have to thing to ourselves "am I going to get locked up for bullshit reasons?" It's the part where we don't get drugs planted on us during a stop and frisk, or tased to death for looking at a cop wrong when pulled over for speeding.
White privileged isn't a club card. It's not the stonecutters with a secret door to a room filled with wonders where the Illuminati plan the future. It's the ability to live our lives without having to think a hundred times a day if about our safety (physical or sexual). It's the ability to go days, weeks or months without thinking about whether we're being discriminated against.
Our privilege is that we don't have to put up with being dismissed out of hand because we can't possibly know what we're talking about, based on nothing more than gender or colour. That's white male privilege, and unless you're completely paranoid, you live it every day.
I agree with you 100% that class plays a far bigger role in today's society than race or gender. If this were a longer conversation I'd throw many other factors in there too. That's sort of what I've been getting at in these comments: this isn't a conversation that can only be had by discussing one dimension at a time.
Those of us who have it good need to learn how good we have it. And we all need to work on treating everyone equally, and with respect and dignity. Regardless of the group to which the person belongs.
That's the multi-dimensional thing. We're all part of a lot of different groups. So maybe we should stop begin dicks to identifiable groups so that, in the fullness of time, people will stop begin dicks to us.
Obey Wheaton's law: don't be a dick.
Really, there shouldn't need to be more to it than that.
