What I said there was no proof of her still being Stasi during her political career. I acknowledge that, though I think it is probable that she still has Stasi connections. Everything I said about her past was factual. It is not open to dispute.
This is of ongoing interest to me. “Beyond dispute,” like “There’s a consensus,” “The debate is over,” (e.g. “global climate crisis”) is a claim often made but not often proved. Can you provide links to sources?
