What will the writer do and what is their motivation for attending the march? Also, what message does the author have for men who might be disrespectful in the comments section?
i'm gonna be there.  my reasons not so "polite"... I am not marching so much FOR anything as i am AGAINST TRUMP.  that's my motivation.  i probably won't even listen to the speakers..  it will be the same talk i've heard at different protests over the years. which is fine - younger folks will get a good earful of information. 
 and for any men who are gonna jump into this stories comments to be rude, disrespectful and ignorant (by god you are in the likeness of Trump) remember - .  Yo Mama is/was a woman.  Yo Mama provided food - perhaps direct from her own body. Yo Mama most likely cleaned your little fannies for 2 or years, while at the same time making sure there was food to shovel into hungry little mouth. Yo Mama protected you.  Yo Mama taught you letters... numbers....words... ideas..  Yo Mama got you to school the first day... waited for your school bus.  Yo mama loved you when you being a jerk... a brat ... a liar ... cleaned up your messes, Yo mama is/was one helluva woman.
