John Boyega has broken his silence on criticism from some Star Wars fans struggling to come to terms with a black Stormtrooper in The Force Awakens. The British actor has one of the more prominent roles in the first trailer for the movie, though it quickly sparked an online backlash with #blackstormstrooper trending on Twitter over the weekend.

However, in a thank you note to fans on Instagram, Boyega signed off by writing, "To whom it may concern. Get used to it :)"

Most of the racist comments were posted on YouTube - often the primary hub for stupidity on the internet - and one user wrote: "The black stormtroopers is probally stealing his comrades speeder bikes and shoot his blaster nigguh-gangster style [sic]."

However, the casting of Boyega was roundly praised and The Atlantic published a piece explaining that a black stormtrooper could exist because the army is based on clones that were not white. 

"The clones were disavowed when order 66 was given and the commanders of the clones gave up their power to the chancellor. The stormtroopers are just normal people. Multi-race, Multi-ethnicities," YouTube commenter Ryan Barry wrote.
