Marches bring attention to the issue.  Bringing attention to it is very important.  Sexual abuse flourishes when no one talks about it.
Complaints are the driver of decreasing such assaults in the workplace.  They are highly effective when made consistently and openly.
Lawsuits are an excellent way to focus the attention of people who choose to ignore or who refuse to process complaints effectively.  
Kicking -- well, if one can, I guess that is highly satisfying in the given moment, but it's actually assault and can land one in a heap of trouble......
I think that it's far more effective to change the public perception of what is acceptable.
