Judging by this thread, you seem to have trouble responding to people in good faith; I don't know if you've got an axe to grind here, but seems a bit pointless to be on a board if you don't want to have a normal discussion. I'd recommend to re-read your own words before posting if you don't want to be misunderstood, too.
I'm more than familiar with trauma from mother/child separation at birth. If your children get removed from you in this day and age, however, especially later on, chances are they have trauma associated to your actions too. Even if they get removed at birth, chances of in-utero exposure to drugs, to domestic violence or neglect are high. Same with being traumatized during family time. You specifically said removal, not relinquishment.
The vast, vast majority of birth parents' circumstances leading to removal nowadays are traumatic to a child, regardless of intent from the birth parents' side. The only exception is parents with really high levels of disability, like Down's syndrome or DiGeorge, but they're the minority, especially since people with disabilities can have a strong support network from their own families who can step in to take custody.
Not all birth parents are abusive or neglectful (especially in cases of relinquishment, but we are talking about removal here), but nowadays many are, and their children can feel about them any way they want to, even if they didn't mean to traumatize them. Same with adoptive parents. You don't get to choose how your children feel about you, or whether they're traumatized by your actions or not.
