This is an argument we're going to hear for the next several weeks or few months as the general election campaign progresses. The implied (or sometimes explicitly stated; see LoF) privilege is that of a white male. Frequently "affluent" or some variation will also be included.

This argument is a variation on the divisive identity politics the Clinton campaign used to successfully sweep the south in the primary, coupled with the "fear Trump" argument. It plays on feelings of guilt and uncertainty in a white population who consider themselves allies of non-whites, and it's very effective.

It's predicated on the notion that Trump is terrible for everyone but white straight cis-males, while Hillary (it is asserted) is better:

We have to accept that Hillary is better than Trump on race because Trump said some mean things and fomented some violence.

We're not supposed to remember that Hillary and Bill encouraged Trump to run, knowing who and what he is, or that Hillary not only fought to pass awful and racist criminal and social support laws, she has as recently as this damned primary marginalized and belittled black activists.

We have to accept that Hillary is better than Trump on sex orientation because Hillary stood idle while some (many) of our LGBTQIPA friends and allies struggled to win victories in courts, while Trump opposes something those victories already covered and will never be able to overturn.

We're not supposed to remember that Hillary held essentially Trump's stance on gay marriage ("up to the states" was code for "opposed, but want to make people think I'm not") until it became politically dangerous for her to do so, or that she as recently as this primary "made a mistake" when honoring Nancy "AIDS holocaust" Reagan at her funeral.

We have to accept that Hillary is better than Trump on gender because she's cracking a glass ceiling and supposedly has fought for women and children for decades, while Trump is a misogynist jerk.

We're supposed to forget that Hillary's economic policies hurt women, and especially single-mothers and their children most, and that her foreign policies result in the mass death and destruction of women and their families, and that she this very primary season said the children of Central America should be sent back through a dangerous journey where they could be raped, killed, or kidnapped and sold into slavery at every turn just to "send a message" to Central and South American countries' people.

One last point.

Listen: I grew up in majority-minority (African-American, Latino and a mix of Korean and Vietnamese) neighborhoods for most of my childhood. I ain't a black dude, and I haven't lived the life of a non-straight, non-white, non-male. But I've come closer to the first two (I had gay family, and gay friends) than Hillary's rich lily-white ass ever has.

Call me privileged for being white--it's true. Call me privileged for being male--it's true. Call me privileged for being straight--it's true. Don't tell me those things are why I oppose Hillary. Don't tell me my opposition to voting for Hillary is from a position of privilege. It just isn't true. Nobody--of any race, gender, or orientation--has the standing to tell me I'm privileged as a response to my objections over Hillary. And they don't have standing to do that to you, either.

It's just a way to shut down debate, because they know their candidate is awful on all the issues that affect all of us.
