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."
His arrest enabled sidewalk counselors to do nothing but see themselves associated with criminals who hide behind their wives. Do you think Jesus would tranfer His assets to His wife's account to hide from the law? I doubt it. All this guy did was sully the pro-life cause for a few minutes of glory. A woman going to kill her child is not going to be swayed by some guy chaining himself to a door. She is more likely to be swayed by someone offering to pray for her child while doing so lawfully as thousands do every year. The pro-life cause doesn't need criminals in its midst.
