Definition: Given a 'poster' sentence and a corresponding 'response' (often, from Facebook or Reddit)classify the sentiment of the given response into four categories: 1) Positive, 2) Negative, 3) Neutral, and 4) Mixed if it contains both positive and negative.
Input: Poster: I will always stand for life and be the voice for those who cannot speak for themselves. There is no one more vulnerable and defenseless than the unborn.  Responser: Ummmm, except when you voted to restore funding to Planned Parenthood when you supported the Omnibus spending bill less than 2 months ago.
