problems with a certain user

So here is the thing:  I am not sure where to post this but I feel like I have had enough.
I saw a post about something and I stated my opinion. The original poster of the topic was not rude or anything; however, we had different views and opinions. I believe that is a good think; to be able to state your opinion without calling someone inapporpirate names. However, another user came and started to call me "dumb", "hoe", and other terms as well as telling me to "stick something  up my butthole". Now my questions is how do I report her and solve this issue? I have realized that this person does go around and make rude comments all over this app. So I think that something needs to be addressed here and not let this individual go around and talk bad about people or about people's opinions. We all have different opinions and I think respecting that should be number one.  If I sate my opinion, I do not want to be harrassed for them as I am being harassed right now!!!
