Bernie Sanders supporters booed and chanted throughout the opening day of the Democratic National Convention — but many Twitter users noticed something about those noisy interruptions.

Seems like Bernie bros mostly chant over black and female speakers#BernieSanders #BernieBros #bernieorbust #DNCinPHL #DemsInPhilly

Am I imagining it or is there more booing and heckling when black speakers are on stage? #DemsInPhilly

Bern bros chanting "we trusted you." Why is it they seem to mostly chant over black & female speakers #DemsInPhilly

So the Bernie folks are shouting over and disrespecting black speakers, women speakers … to what purpose? #DNCinPHL

A bunch privileged white lefties shouting down black and female speakers for their (ideological) impurity: bad optics, but perfect metaphor

— Bryan Kessler (@kesslerbs) July 26, 2016

Pay attention to who they picked to open up the convention. BernieBros are playing themselves by booing black, Hispanic and gay speakers.

This whole "screaming over black speakers" thing is not a good look.

Funny, this is not the convention I expected to see old white people screaming over black speakers, complaining about being marginalized.

When a black man, who is a civil rights hero, is talking about civil rights, maybe shut the fuck up for five minutes about the TPP.

Uh, white ppl turning their backs on Black speakers talking about racism and voting rights is disrespectful as fuck https://t.co/zbq8lipcb2

@sansdn like this is my blackness speaking but a bunch of privileged white kids booing black speakers isn't racist as fuck what is

@abbiewastaken some whiny suck babies chanted over women & black speakers in particular, sometimes before they even spoke

Dollars to donuts same Sanders diehards chanting over women, black, and hispanic speakers are baffled why Sanders didn't get those votes…

@JessicaValenti I was expecting this as the Busters were shouting loudest at Black speakers earlier :O

People at the #DNCinPHL are chanting #BlackLivesMatter but apparently they don't think black speakers matter all that much.

Berners booing black speakers provides a portrait of why the campaign did so poorly with POC. It's not coincidental folks.

Can we just not chant when black speakers are speaking? Can we just not? #DemsInPhilly

— Brinda Estrella (@BrindaStar) July 26, 2016

Pretty tired of trying to hear black & brown speakers thru the tantrums of intransigent neophytes. Pretty fucking tired. #DemsInPhilly
