I agree. Genes contribute to mental illnesses but they are not the sole cause. I have a problem with people who deny the importance of social environmental and life events. It's like they're dismissing the crap I went through. It's hurtful and invalidating. I think people sometimes overemphasize genetics because it is a convenient way to escape responsibility. It's easier to blame an illness completely on a person's brain than to admit that someone might have done something to the person.
