Depends on what exactly we’re talking about here.

Sometimes it is constructive to bash individual men for their behavior. They’re bullies. The oy way to stop a bully from bullying is to check them. Bashing can accomplish this since being seen as inferior is what they fear most. This about power dynamics, not hating men.

Sometimes it is beneficial to bash harmful ideologies coming from the manosphere. Again, this is a check because unchallenged thoughts that are repeated often enough become part of the cultural zeitgeist and gain favor and false 'truth’. We’ve seen this dynamic before too, usually around issues of crime (also genocides). Most recently the Rittenhouse trial. Mobs of violence are whipped up around this phenomenon. So when the incels say, “women should be given out to men so betas can have sex and not be so angry", which they are, ad nauseum, and it’s picking up steam. And women say, “men are scum. I’d kill either myself or them before I’d have sex with their scabby asses", it’s not about hating men, it’s about rejecting the belief that men are owed women, preserving ones autonomy, and working against the never ending march toward Gilead. It’s about stopping a play for power.
