Opreation Rescue was by far the highest profile activist group in that moment. They were not radicals shunned by more moderate pro life people. They had enormous support.
Wichita is stuck in Kansas, a conservative state yes, but the average person you'll meet there is very similar to who you'd meet in any of the major metro areas.

My family's church went into schism in response to the Tiller murder. The strongest condemnation on the anti murder side was basically "they shouldn't have done that in a church." I cannot recall a single person out of hundreds that condemned the murder (or bombing) itself directly. The closest is my father, who maintains a "abortion should be outlawed except if rape" perspective. Additional useful information here is he failed to know my older brother was sexually abusing me in his own house.
I know "what if" style contrarian takes are an addiction on this forum, but please, do not engage in hypotheticals on this issue if you are not actually familiar and plugged in. You are doing evil purely in the service of some forum warrior "what if I actually have the smart take here" nonsense. These people know they're hypocrites drowning in dissonance. It's central to their mindset. Not only do they not care, they will double down on it every time.
