Can we have an honest discussion about the facts of slavery?

Slavery in general goes back as far as documented history involving every major culture and every race/gender/etc. Muslims held millions of white Europeans as well as African slaves for centuries as an example. Europeans first started to enslave other white Europeans until their neighboring countries became too powerful to exploit each other for slaves. Slave comes from the word Slav or Slavic, an eastern European group of people. When they could no longer easily enslave other Europeans they turned their attention to Africa.


As it pertains to the Atlantic slave trade:

- Slavery was taking place in Africa long before Europeans started buying slaves. More slaves were held in Africa than were sent elsewhere.
- The Portuguese, British, French, and Spanish started the atlantic slave trade
- The overwhelming majority of African slaves were captured and sold by other Africans as a result of lost wars and tribal conflicts
- Europeans bought the slaves from the coast and rarely went into the interior of Africa to capture slaves themselves
- About 12 million people were sold as slaves destined for North/South America
- Only ~3% (~500,000) of slaves were brought to what we now consider the United States. The largest percentage of slaves went to Brazil
- In contrast to 112 million slaves taken from Africa to the middle east, most of whom were castrated or the women taken as sex slaves
- Educated religious whites from Britain, Portugal, and America started the movement to end slavery not only in their countries but around the world

Given these indisputable facts. Can someone explain to me how a white male currently living in the United States is in anyway remotely responsible for a practice as old as humans that ended almost 200 years ago and that this justifies some sort of reparations or apology.
