The whole performance with Stonewall's witness and his dog / mum / support person was a turning point for the organisation I think. It was a bit like the wizard of Oz. All of a sudden Stonewall wasn't this polished, professional, well-trained, reliable source of legal knowledge. Just the most underwhelming bunch of inarticulate, mean-spirited keyboard warriors, terrified of being called out on their actions.
The damage to Stonewall's reputation was done, and things aren't going well for them right now. I do think Alison is raising valid points that need to be flushed out in court. Whether that translates into something punishable by law remains to be seen.
