Is it possible that antidepressants have some extremely subtle transgenerational epigenetic effects? Maybe, but comparing healthy patients to SSRI-treated remitted depressed patients is a bit of a red herring anyway. The real comparison would be between SSRI-treated patients and untreated depressed patients, because healthy people aren't prescribed SSRIs. We do know untreated depression is very harmful to people and their families, so speculating about immeasurably small negative effects of SSRIs while ignoring the massive and very real cost of untreated depression would be a mistake.
I see it very differently, as you are focusing entirely on the parents and completely ignoring the children. If the untreated patients weren't going to have kids, the question is only whether or not the children are happy. If the children of parents with antidepressants are more likely to require antidepressants themselves, I'd say that's indicative of a serious problem.
I'm not aware of any evidence that this is the case. Do you have any evidence, or are you speculating worst case scenarios?
Regardless, I think it's shortsighted and in poor taste to suggest that there is a problem with parents on SSRIs having children, particularly without any evidence to support your claims.
SSRIs vs Untreated depression is a false dichotomy. There are many treatments for depression.
I think these are the sorts of questions that would be useful to know when really mass-prescribing drugs to humanity. To be clear, I'm not suggesting that the drugs are inherently harmful to offspring - but it seems like something that would be good to know. If the parents have a chemical dependency, what does that mean for the children?
