A useless symbolic gesture that is only good for bringing attention to one's self. He would be better off raising money to put pictures of sonograms on billboards near the clinic.
Protesting are generally symbolic gestures. As one having been involved in rescues, risking arrest was a means that allowed sidewalk counselors time to talk to women waiting to get in. Dozens in CA went to crisis pregnancy centers; of those, many delivered babies. We held some in our arms. Glad you think those actual babies' lives were "useless."
Oh, please, if I'm about to be murdered, don't put an image of another person's image on a billboard. If we're being persecuted unto death, that may help someone within my peers of the persecuted, but it ain't gonna help me.
That's the problem with folks who turn "love your pre-born neighbor" into an abstract, depersonalized "social issue." Sorry, folks, these babes in the womb only have a few weeks or months to live during the highly risky first trimester. Traditional pro-life activity tends to only help future babes; not ones presently alive.
