"Anyone can be reasoned into doing that which would fulfill the most and strongest of current desires. However, what fulfills current desires is not necessarily the same thing as what is right."

You seem to be overlooking the desire to be (seen to be) reasonable in itself.

"Anyone can be reasoned into doing what is right with enough argumentation”

...is probably false. But if reasoning and condemnation both modify bechaviour, however imperfectly, why not use both?

I subscribe to desirism

How does that differ from virtue ethics?
