All due respect: I’ve never understood this argument. I understand Taoist traditions, but I can’t comprehend a “good dark side user”. Love and passion aren’t equivalent to darkness, they just lead you to it if you aren’t careful.
Dare I say it, I don’t think the Jedi did anything wrong during the Clone Wars. A genius outsmarted them. Had Palpatine not been involved Anakin would have either peacefully left their order or broken off with Padme and firmly joined their cause. I just can’t see the Jedi losing the PT because they were “too good”.
The issue as many see with the Jedi’s approach is that they taught their students to essentially suppress any and all emotion that leads to the dark side. That’s unhealthy, and in the end we see that it leads to the dark side as well.
Personally, I feel that the Jedi are wrong about not allowing romantic love. However, I don’t think it means they are wrong to teach their students to resist the dark side, as I don’t equate romantic love with automatically being connected to the dark side. In my opinion, one can be fully aligned with the light side of the force, and still be in a relationship with someone.
