As far as Benei Banim, it is entirely unreliable on his grandfather (Rav Henkin zt’l) views, which the author by and large is at odds with himself. Before using him as a citation check out his seforim, including his teshuva on the permissibility of mixed dancing, see what he says and decide if this is a person you want to quote. Or the funniest teshuvah he has is about – and I am not making this up – whether you are permitted (yes, permitted!) to say “Zatzal” on the Satmar Rebbe ztvk’l, or is it prohibited to say Zatzal on him, since Zatzal would imply that he was a Tzadik. I am not kidding. He really has a lengthy discussion about this.
