After Sen. Kamala Harris, D-Calif., was interrupted not once, but twice, by male colleagues in a short succession of days, liberals leapt at the opportunity to champion her #persistence in the face of alleged sexism.

Even the mainstream media slyly hopped on the bandwagon, subtly betraying an unspoken sympathy. "Once again, senators cut off Harris as she rails on Sessions," a CNN headline declared. The Hill wrote, "Kamala Harris questioning cut off for second week in a row". People Magazine headlined its story on the dustup, "Sen. Kamala Harris Fires Back After She's Repeatedly Interrupted by Male Colleagues During Sessions Testimony." Harris even earned a Twitter Moment titled, "Male colleague interrupts Kamala Harris at Sessions' hearing."

But where were those headlines for Betsy DeVos?

The education secretary was interrupted repeatedly by men during her confirmation hearing, and on occasions since, but the Left has celebrated those interruptions, not denounced them.

Here's what I wrote about this glaring hypocrisy back in February:

Consider the way in which three different male late night television hosts ruthlessly mocked an out of context soundbite of DeVos discussing guns in schools, laughing smugly at her implied stupidity. The clip itself was only made possible by Sen. Chris Murphy, D-Conn., cutting her off as she elaborated on an entirely valid point about the importance of deferring to state and local governments.

Powerful male television hosts cherry-picking a clip in which a male senator cut off a female presidential nominee, inviting the country to laugh at her supposed lack of intelligence? Let's be honest: this is a clearcut embodiment of the Left's definition of sexism.

Remember when Bernie Sanders interrupted Hillary Clinton in a debate last year? Liberal websites from Mic to Vox immediately pounced on his behavior. If it's sexist to interrupt women, it's not just sexist to interrupt liberal women.

Just last week, liberals celebrated clips of Sen. Jeff Merkley, D-Ore., interrupting DeVos. The Hill headlined its coverage, "Sparks fly between DeVos, Dem on private school protections for LGBT students". Sen. Sanders himself interrupted DeVos during her January hearing in another moment that was celebrated by the Left. Here's a video from that same hearing of Sen. Tim Kaine, D-Va., repeatedly interrupting DeVos as well.

If it is sexist for men to cut off women, it is sexist for men to cut off women.

That the mainstream media eagerly covered interruptions of Harris, yet never attempted to do the same for DeVos should tell you from whom people sitting in coastal newsrooms take their cues. Worse, the Left's impulse to cry sexism over interruptions of Harris but not DeVos means either those complaints are examples of insincere opportunism or that so-called feminists do not care about conservative women. The truth is probably a combination of both.

If feminism is to be taken seriously as a vehicle for fighting sexism, the movement must demonstrate it is actually interested in doing so, even and especially when the direct beneficiary of its efforts will be a conservative women.
