I recently read Days of Rage about the various groups committing political violence during the 60s and 70s. Weatherman, Black Panthers, Black Liberation Army, etc.

I don't know if there was really a 'message' more than just reporting what 'happened'. But, I have to say I came away with the idea that that kind of political violence is futile. Non-violent political action seemed to have MUCH more beneficial action than any bomb. (of course it wasn't as clear-cut between non-violent groups and revolutionary groups at the time)

Maybe thats only because I just read the ONE book.

A famous paper argued that, from 1960 to 2006, nonviolent resistance was twice as likely as violent resistance to achieve its goal: it's a paper that most activists I've ever met had heard of. The reasons are largely the perception of violent resistance by the bystanders, meaning the population.

However, there have been a number of criticisms to the paper about data coding, methodology, and interpretation/motivated reasoning. Recently, the author has also acknowledged that governments have adapted since 2006: her data says nonviolent resistance is still more effective, but that the success rate has cratered.

I tried to find some of the criticisms, but it's recent, so all AI generated, so I won't link before reading, but the criticisms I'm aware of I think are robust. All this to say, the idea that nonviolent resistance is more effective is comfortable and feels better, and there is a paper that says so, but your examples and those of a child comment are not about resistance to armed colonial oppression and it's not enough to form a blanket opinion about violent resistance.

The general impression from talking to people who live then (I was a baby in the 1970s so I knew/know a fair number). The violent groups were looked on as weird or kids who needed to grow up - they were ignored for the most part other than cheering on what the police did.

There is a reason Rosa Parks was chosen to start the bus boycott - she comes off as "just like me" to the average person. Thus when she couldn't take it anymore the rest of America didn't write her off.
