As someone who takes antidepressants, I don't really see a problem with it.
There is no doubt exercise can be powerful. Saying so is doesn't dimish the condition. Of course medication has a place and the video may be ignorant but it is nothing worse than that. It is not offensive.
It's like someone with 2 diabetes. The medicine can be effective but so can losing weight and improving diet.
Drugs aren't the be all and end all. It's the culture that if you are ill, you need drugs but that isn't necessarily the case.
It's almost like you are judging how I'll people are by the amount of drugs they take.
