This is very strange. From the article, the guy’s been protesting for months. He shouts obscenities at passersby, even if they are just walking past. This PP does not perform abortions. No mention if he is with any particular organization or just by himself. My guesses:
A lone nutcase
A lone nutcase who wants to make pro-life people look bad
What I find strange is that they say the man first attacked the protestor. So isn’t this a case of self defense?
