My view is it's sort of a balance. There's a place for confronting negative thoughts but it's possible to spend too much energy doing so which can also have negative consequences.

The problem is that you can't "weed" your mind, that's not how minds really work. It's not a garden at all, it's a learning system. The things you pay attention to are also the things which become more prominent. Attention is ultimately sunlight and water for memories if we need to use a gardening analogy.

The problem really comes when the memory becomes intrusive. At that point you're forced to do something to tackle it because it's growing anyway.
