Love the Sinner, Hate the Sin?

I believe that the popular statement "love the sinner, hate the sin" is hollow.

It is rooted in self-righteousness. It implies that, "since I am not doing that particular sin, I have the license to judge his/her actions".

No, the person who is making the statement is merely parroting a popular line, because pure love is unconditional, and it does not look at a person through the filter of his/her action, regardless of how good or bad it is.
