People who want bloodshed tend to say this… It’s melodramatic.
You could say that about anything classified as human progress. How did we improve things so that people could have electricity and safety? At the cost of deaths and suffering by everyone who built the Hoover Dam and similar projects. The same goes for "stop killing patients by going dirty from corpses to the delivery room," even when we knew it was unsafe. There is always death and blood related to any topic. How do you think you got the device you are communicating with? Through the death and suffering of someone in Congo, mining cobalt, and someone working themselves to death in a factory.
I have lived through the normalization of gay rights in Norway, and saying that it was a process marked by blood and suffering is moronic. It was painful, unnecessary, overdue, and many other things. But saying that it was a bloody conflict is just not true, at least not any more than many other progressive movements. So progress doesn't have to be violent.
You could say that this is not the lived experience of many people, and that is true. But that doesn’t automatically mean it has to be so for everybody, and it does not have to be inevitable for any cause. It’s not statistically more violent than many other things.
I’m getting tired of the violent and angry rhetoric people spew without pushback. Stop idealizing and glorifying violence and conflict to solve any problem. It seems more and more to me that this is violent ideation first, with the cause being secondary.
