Need to rant! Why are people so opinionated when it comes to babies?

I've had a hard day baby has been very difficult definitely not loving this weather so we've been laying in bed most of the afternoon and I've just vegged during naps. But of course my mind has wandered. This happened a couple of weeks ago and I don't know if I'm just being over sensitive but I got an email prompt for feedback and it's brought it all up again. I am a first time mum and I know when I go to baby classes both antenatal and post partum that I ask a lot of questions but it's how I process information and I always want to make sure I am being medically safe. I did an online weaning workshop recently just to start getting the info together and overall it was very informative. However one little blip is the thing I remember most about the class that makes me never want to do another class with this organisation again. We went through parent led and baby led weaning and I asked is there any medical reason that we can't do a bit of both depending on baby's preferences, time available or just to experiment a bit. I don't think that's an unreasonable question to ask especially when like me you have no idea what you're doing I just wanted to make sure if we did that I wouldn't be harming my baby. The workshop leader who was a midwife as well just shot me a look and said "if you asked that in a baby led weaning workshop you would be shot" I just found that so unhelpful, didn't actually answer my question and was a bit judgemental. I don't understand why she chose to answer like that and she wasn't happy with my follow up which was I don't ask Facebook for medical opinions. I just think we mums are under so much pressure already and even if we don't agree with each others methods we at least have the common courtesy to show each other respect and support each other regardless and I couldn't believe this was what I got from a medical professional literally running a class to help people. (P.S I filled out the feedback form but I don't think they are going to like it)
