Your assertion that it's not, is not sufficient. Especially when the very idea of having a talk caused so much tension. If it's a non existent problem, this talk would've been given no more attention than a presentation about bigfoot.

Such (pro)active denial usually indicates the denier has something to hide. Now that may not be the case here. But assuming you're right about this not being a Google problem but just small pockets like sexual harassment and racism.

Doesn't google still hold talks about racism & sexual harassment? I'm pretty sure they do. So why the voice against this talk, and this issue specifically?
