I similarly condemn such actions. But unless we are in a position to enforce any change in behaviour on Serbia then being unhappy on a web forum doesn't count. It's as useful as "thoughts and prayers".
Take some meaningful action away from this forum and we'll see. I am not in a meaningful position to do so unfortunately.
Action isnt the only measure of meaning or the only determinate of caring.
Caring exists on a spectrum, and isnt black and white.
Thoughts and prayers are a form of caring as well, and an important one. It isn't always what a utilitarian wants, but it is part of a package deal when working with real humans with emotional and social lives.
I think you and I are largely in agreement in that caring is good. Without such caring then no such meaningful actions would ever happen. We need to care, it is a good part of society. But care without action can be ignored.
So as far as Serbia is concerned "no meaningful consequence = the world is fine with.. just about anything."
