Calling Whit an all-star is as fatuous as calling Espinal one. The facts have been laid out for you - Whit has been ice cold for a month and a half, he's hurt and he's never hit power pitchers well, let alone this year. What you're countering with is pure conjecture that's unprovable.
Given all of the facts in front of us, it was a terrible decision, and conjecturing that better, more experienced managers would have made the same mistake is not a counter-argument that absolves Schneider.
As Seath mentioned - if a better pinch hitter was available and used, the move would have been easier to rationalize.
