Those things you mention above have happened and still happen in Scientology, so the damage would depend on what the individual experiences were and how they were coped with. Some people do better at it than others.
I think it's healthy - and hard at first - to accept there is damage. Why do you think that writing stories here brings up so much emotion? IMO it's because the damage is finally allowed to manifest and thence to be healed.
It feels like the pits to say "I was damaged" and allow that thought to bring up what it needs to. It feels like you are a complete and utter failure per Scientology standards, which is the hardest thing of all.
Yes I was damaged, badly so.
No I am not so damaged now. Because I am prepared to admit it, talk about it and find ways to heal it. I have been doing it for 10 years. ESMB's environment brought up damage I did not even realise existed! And in a short time, by experiencing those issues in all the glory of tears, anger and laughter, they are gone. I realise it will always be an ongoing thing, finding those hidden pieces of indoctrination, however compared to when I originally left I can say I am a different person.
We don't need to go putting labels on things. Who exactly is offering this datum you say is creeping in? We are all individuals, with different lessons. I know some people so damaged by Scientology that it breaks your heart. I know others who coped in a different way and seem able to go on with life quite happily.
Sure compared to the atrocities this world can offer, it may be small potatoes. Yet each person makes up part of the whole, and to the extent they are not healed, we all suffer to some degree.
