I don't think it's surprising that a movement that advocated successfully that the accusations do not require evidence, has created an environment of fear.
I don't experience it that way, but let's assume for the sake of argument that you're right.
The topic of discussion was whether #metoo was a net positive or a net negative for women. Simply saying that it has created an environment of fear does not address this question at all. Even if true, perhaps having some people be afraid is a net positive for women in the workplace? Or perhaps it is negative, but other positive outcomes of the movement outweigh it?
