Actually you're both wrong.<quoted text>
Nobody believed that you idiot. That was about taxation, nobody claimed that slaves were 2/3 persons. DAMN you're stupid No Relevance.
1) The plantation owners wanted to count each slave as 1 person. The Northerners didn't want the slaves counted at all.
2) This led to the 3/5 compomise, not 2/3.
3) The issue was Congressional representation, not taxes. Because representation in Congress is based on population, counting slaves as whole people would show a higher population and thus more representation in Congress.
