The truth about antidepressants is that the majority of people with depression that respond to an antidepressant would also have responded to a placebo. This doesn't mean that their depression isn't real or that antidepressants "don't work". It just means that placebo has a relatively high response rate in trials for depression. The hate is (among other points) because they are only arguably, marginally, better than placebo, and antidepressants also have real side effects (activation syndrome, increased suicidality, sexual side effects, withdrawals, etc.) over placebo.
