The problem is that you only see one option in regards to the kaffir slaves i.e just free them.
What am saying is yes we can free them but thats not the only option we have.
Also it is not the same reward nor value as freeing a Muslim {Your implying that it is}
You said "Islam came to dry the sources of slavery"
Your statement is very contradictory.
As someone said before provide your proof for this statement.
