Not sure if you're just going off my words or if you watched the actual panel, but I'm pretty sure that crying bit was more hyperbole than any specific example given he was talking about himself. Not really sensing any "toxic masculinity" or anything of the sort.
Never got the sense that he was against Superman expressing emotions. I'd say the opposite really given that he brought up his Superman manifesto and the main idea behind it was that he'd prove just how relatable Superman is. Bendis also talks about what Superman's personal choices are and how being Clark and being a reporter was the first thing he ever really picked for himself.
One bit of completely harmless hyperbole doesn't erase that it seems like Bendis is far more invested in Clark as a 3 dimensional person (emotions and all) than I've seen with most writers in a long time. So I really can't relate to where you're coming from with this.
