In Monday's article, Stacey Patton, a history professor, and David Leonard, a professor in gender and race studies, argued that Schumer shared striking similarities with Donald Trump - who has recently come under fire for his controversial comments about Mexicans.
Patton and Leonard write that both the comedian and the billionaire "draw on shared cultural stereotypes and use dehumanizing language that gives life to an ecosystem of racial fear and violence".

The piece continues: "This rhetoric isn’t just ugly. It contributes to a worldview that justifies a broken immigration system, mass incarceration, divestment from inner city communities, that rationalizes inequality and buttresses persistent segregation and violence.
"Yet nobody wants to take responsibility for spewing rhetoric that breeds the fear that results in soaring gun purchases, that 'inspires' monsters like Dylann Roof to craft a manifesto with deadly consequences."
This is not the first time that Schumer has been called out for her "racist" jokes.
Just last month, The Guardian wrote that Schumer "has a shockingly large blind spot around race", adding that her stand-up show "repeatedly delves into racial territory tactlessly and with no apparent larger point".
But many people are not buying the accusation that Schumer's jokes can be blamed for atrocities such as the Charleston shooting.
