I fail to see the connection between ~"don't see exercising as a golden bullet against depression" and what you claim I've said.

you said "[exercise] might be good for a lot of depressive people, but definitely not for all."

Which is dead wrong. Exercise is good for humans, depressed or not.

You also said, "Before I turned twenty I met two people my age who took your advice and exercised until ambulances had to pick them up (literally). "

...apparently as a warning that exercise is dangerous. But as you can see, it's a ridiculous statement.

Sure, people should see a therapist. They should also exercise. Go for a walk. Move around. They should also gain some sleep discipline. Those are easy to start with. There's no mutual exclusion here. Just because someone is exercising and sleeping right, does not mean they cannot talk to a therapist.

i read it as "might be good enough", which is entirely closer to the meaning that parent was trying to get at, I think.

Also I don’t think gp was trying very hard (at all?) to understand this point

It's easy to become dependent on exercising, push too hard, get injured, and struggle while you can't exercise. Moderation can be difficult for some of us even with something like running.

Here is where the benefits of promoting exercise far outweigh any risks that people who exercise may experience. There is no need to hedge here. Exercise might not cure your depression or even help it, but in general, exercise has been shown over and over again to be one of the most effective things that you can do for mental and physical health.

I can't really agree with this, there are definitely lots of negative avenues from exercise if not done right.

Generally, hopefully, most people will do exercise more or less "right", but this is not a safe assumption.

That could be said of almost any healthy thing.

It's very easy to over exercise if you haven't started yet, I seriously hurt myself after a couple of weeks of running, as my body was nowhere near prepared for it.
