Air passenger's viral post seems to show racism is alive in America - but is it real?

A Facebook post that claims to expose casual racism in America has become an massive viral hit –but some social media users are challenging its accuracy.

The post details an incident where a white female traveller asked a black passenger to move out of her way while boarding a flight in Arlington, Virginia. Walker, originally from Philadelphia, claims that the woman asked him to move from the queue because she assumed he did not have first class priority boarding.

She is alleged to have said: "You may be in the wrong place, you need to let us through. This line is for priority boarding."

When he presented the his boarding pass the woman she replied that this was probably because he was a serving member of the military – insinuating that black Americans are too poor to buy first class tickets on their own.

His response reads: "Nope, too big to be in anybodies [sic] military. I'm just a n***** with money." At this point he claims that the crowd started cheering and applauding.

So far his post has been shared over 200,000 times on Facebook. Many say the tweet is indicative of prejudices still widely-held by white America.

Jasmine Battle said on the post: "White privilege is something else!!!!! Smh! I'm glad you stood your ground!"

Gantt Nikia replied: "Smh!!! (They) be looking at me crazy everytime... Like I skipped the line or some shyt! I just smirk n keep it movin."

Some claim the post outlines an event that did not happen and some took to Twitter to voice their skepticism:

Black Twitter users have hit back and said this is just one of the many challenges that face minority communities everyday in America:
