No it doesn't. It has in fact nothing to do with that claim. If islam regulates slavery, it's obviously making it legal and pushing it.

Compare it with this, suppose some republican came to power and decided to legalize drilling through nature reserves but makes a big public statement discouraging it. What is that person doing ? Pushing it, or discouraging it ?

There is only one, and blatantly obvious answer : islam is pushing slavery. In theory, as you confirm yourself with your statement showing that islam regulates slavery. In practice, because of what is happening in Saharan Africa, Yemen, Kuwait, etc.
