We have a bit of ambiguity in the term of socialism, one being a ideology, the other being the act of making something social, or distributing it socially, another wrapped up in social authority, another lending to social objectivity. But, for now, lets set that aside.
Also let's set aside the 'taking' part of taxation and see that you do agree about distribution. I think you can see it is a mixed system. I don't think either of us would like the system as a whole due to various reasons. One that bothers me is that the system tends to be a centrist position.
Why do you see social engineering as moral?
The rest of your comment doesn't really address the the question I was attempting to ask, and I am interested in your thoughts on it. I will try it in a different way.
If people of ability like the rewards of voluntary system X, and people of need like the rewards of voluntary system Y, how is system Y going to be anything but a system filled with need? You mention the right resources, but the need is going to be large, and most of the people of ability, and therefore much of the generated resources are going to be in system X.
