I am so sorry you feel that way.
I do think, from my understanding, that there is a big difference in adoption now and decades ago in terms of what children are told, how it is treated, contact etc. So maybe people feel that the advice may not be as applicable???? (as most adopters, if not all, have adopted more recently) That is definitely a question not a statement. Though I would certainly hope you would not be shot down for giving it and definitely not bullied.
I personally think it is just as important to hear the negatives as well as the positives. Not all adoptions are happy ones, not all are positive, not all fulfill what people wanted out of them. It's important to hear all to prepare for all eventualities because just because for one family it was all happy endings, doesn't mean it will be for another and vice versa.
I think the nature of this topic, whether you're an adopter, adopted, or a birth family member is so emotional that people do get more upset, defensive etc and that does not always result in positive posts but we're all in the middle of it aren't we, so we can't switch it off.
I go back to my suggestion of us all highlighting who you are asking/talking to in the post title to get the most support/validation/best answers. The other thread for those previously adopted, last time I looked, seems to be going well.
Once again I'm so sorry that it's good for many but not all.
And this post was definitely meant as one of good will. I'm sorry if any of it has not come across right.
