Watch: Colin Kaepernick travels 'home' to Ghana to find his independence

Colin Kaepernick remains unfazed by the fact he remains unsigned by NFL teams.

The former 49ers quarterback tweeted a minute-long video Tuesday of a trip he took to Cape Coast Castle, a former slave trade hub in Ghana, and questioned the celebration of Independence Day in the U.S.

How can we truly celebrate independence on a day that intentionally robbed our ancestors of theirs? To find my independence I went home. pic.twitter.com/hniYGJeLxG

"What have I, or those I represent, to do with your national independence?" - Frederick Douglass. In a quest to find my personal independence, I had to find out where my ancestors came from. I set out tracing my African ancestral roots, and it lead me to Ghana. Upon finding out this information, I wanted to visit the sites responsible for myself (and many other Black folks in the African Diaspora) for being forced into the hells of the middle passage. I wanted to see a fraction of what they saw before reaching the point of no return. I spent time with the/my Ghanaian people, from visiting the local hospital in Keta and the village of Atito, to eating banku in the homes of local friends, and paying my respects to Kwame Nkrumah's Memorial Park. I felt their love, and truly I hope that they felt mine in return.

Kaepernick created controversy last season when he chose to kneel during the playing of the "Star-Spangled Banner" as a way to protest police brutality against minorities. 

Born in Milwaukee and raised in California by white foster parents, Kaepernick said he knelt during the national anthem because he would not "stand up to show pride in a flag for a country that oppresses black people and people of color."

He has since said he would not continue his protest of the anthem should he be signed. But NFL teams don't appear willing to take on what could be a distraction despite Kaepernick's talent that most believe exceeds that of other quarterbacks like Austin Davis, Ryan Fitzpatrick and E.J. Manuel, who signed as free agents this offseason. 

Clearly those signings have not caused Kaepernick to tone down his political activism, but isn't he simply exercising the very freedoms other Americans were celebrating in the form of beer, hot dogs and fireworks?
