#BBCtrending: How two friends started a hashtag race row
How did two friends from Florida start a US-wide race debate on twitter?
Daniel Brack, who is black, and Josh Prickett, who is white, started tweeting each other using the hashtags, #IfIWasWhite, external and #IfIWasBlack, external. It started with jokes at each other's expense but to their surprise, it kick-started a heated discussion on race across the US.
