The accusations against Brand stem from as long as 18 years ago. A few women have come out of the woodwork at the same time after all these years. A co-ordinated attack which he has strongly denied and stood tall, much like Dan Wooton did. I am not too sure of Brand's politics in terms of being left or right (seems like a lovey lefty to me) but I know he talks a lot about controversial issues like vaccines. I have seen absolutely no evidence to support the accusations.
Edwards accusations were far more recent and as soon as they surfaced he played the mental health card, made no denial and swiftly disappeared to a mental health facility. The BBC confirmed it had seen the messages between the two. There has still been no denial fro, him and his wife basically admitted it. To me, that implies there is truth to them. I am not too sure of his politics, but as a BBC presenter I'd assume he's a lefty Remainer who pretends to be impartial but I never really looked into it.
We should wait for the evidence to emerge for both, but the nature of the attack on Brand appears well co-ordinated, random and viscous whereas with Edwards it seems like a concerned relative of the alleged victim. The time it took for Brand's victims to come forward (all at the same time) is also HIGHLY suspicious to me. Seems like a way to stain his character and shut him up as he has clearly gone after some powerful entities. Nobody needs to shut up Edwards, because he is basically a puppet who reads from a teleprompter provided by his mainstream, establishment masters in exchange for cash extorted from the general public.
Hope that clears things up.
