This does not follow.
Let's say making value judgements may in general make ones feelings more intense at times (I am not sure of this, but I'll give you the benefit of the doubt). Yes, having intense emotion leads me means I do not think as clearly at the moments I have those feelings.
However, those intense feeling have value in themselves, in that they define who I am more completely. If they are part of my subconsious, denying their existence, and repressing them does psychological harm (which leads to more intense feelings, at inopportune times).
Rationally speaking, why would one choose a certain profession over another? Why would one choose a particular lover over another? If you did not ever have intense feelings one way or another, how do you know what will provide you with the energy and commitment needed to do difficullt things?
