That's not unreasonable. I perhaps could have worded it more neutrally. Though IMO scumbags need to be called scumbags.

It's not about "taking revenge", it's about setting the record straight. As mentioned, I don't think this person should be lionised. And I think that the constant idolisation of this (bad) person does the industry and history a disservice. And I think that there are people who might be curious about the facts of this person's track record if they were alerted to them. By a comment like mine.
