Sorry you had a bad experience. I think it is a universal nature of the support groups. Matters at hand tend to be sensitive and cause of big feelings. Because of that sensitivity, people take offence easily and hear criticism pointed to them, where it is not even intended.
Every group have their own truths and differing opinions are not welcomed and are easily perceived as an attack or trolling.
I have never seen a support group, in real life or online, where this wouldn't be true.
Try to find a support group, where 'gospel of the group' is closer to how you feel or if you do get something out of that group and want to continue going, be very careful in voicing your opinions.
It is how it is, support groups are not places, where differing point of views are much appreciated.
