I think he tends to go off half-cocked, and be very accusatory, when it's really not fair or appropriate. The David Tennant incident is a good example, it's not difficult to slightly modify your language to show the connections to safeguarding issues without basically calling someone a pedophile. The latter isn't effective, but also, maybe more importantly, it's not true. I am sometimes surprised that as someone who is a subtle writer, he doesn't manage to do this and I think it must be due to lack of reflection in the moment. There is good sense in the advise not to send letters, email, Twitter comments, in a hotheaded moment, but to reflect a bit first, for almost everyone. Social media of course encourages the opposite.
That being said, I really hate this "man, keep your nose in, this is a woman-issue" shit. Especially when it's clearly an all society issue with many different facets. There are men being directly affected by this, men have mums and sisters and wives and daughters and female friends, men have an interest in a just society, in medical malpractice, in a robust democracy. And in the next breath you will often have the same women who say are decrying how men don't support women's issues.
I also don't think that it's unreasonable that an autobiography mainly talks about the person the book is about.
