How is that a choice? People from Europe were already years ahead and had ships, weapons and horses. People from Africa had nothing so they were overtaken easily. Black people fought back but they were either captured or killed.
Actually you didn't make an argument... you declared it wasn't a choice in stern and demanding self righteous tone... which is cool because slavery was bad... but thats not an explanation.
Actually, you said “there’s your counter argument”. You can only make an counter argument against an argument. So, saying I didnt made an argument is quite stupid.
