I mean, you asked for proof that you'd said something and there was none, so you'd have been right to be arguing about that. It's one of the actual benefits of internet fora - there is a written record of everything. I put my hands up and said I got you confused with the person who started the abortion and surrogacy are the same line, which many people responded to, and apologised because I didn't want to misrepresent what you had said.
Some things that you did write were rather argumentative and caused me to think you were trolling people. For example, saying that things were "one-offs" as a means to dismiss them ("what's that? One case?"), and then laughing again when two more examples were linked. The same argument could be made for sending kids swimming in shark-infested waters because there are only a few news articles about people getting eaten by sharks. You can't just dismiss all anecdotes without backing it up with data. There are legitimate concerns, but I don't think that anyone knows how significant they are.
Another thing that seemed unnecessarily combative as well as poorly informed was denying that pre-birth experiences and pre-natal bonding don't affect development and long-term emotional health (on page 8 of this thread). They categorically do. Google: "Studies indicate that prenatal stress is linked to adverse neurobehavioral outcomes, including social/emotional and cognitive difficulties during childhood." However, it is not clear that there is research into how this would affect babies born via surrogacy. I have been able to find a small study that seems to broadly indicate that surrogate children have no higher incidence of emotional difficulties than naturally conceived children. There isn't too much other research into the area, but again it is a legitimate concern.
Similarly, saying UK surrogacy is fine when actually the majority of UK surrogacies are from other countries (mainly the US, which we've agreed might be much more dubious and open to exploitation). Most people wouldn't know this stat though, so that's fair enough.
It's clear that you have a much more nuanced opinion than you initially presented with. I genuinely did think you were being intentionally argumentative.
