Do You Have to Be Putting Something on the Line, Put Yourself at Risk?

Do you have to be putting something on the line, put yourself at risk somehow, in order to be in solidarity with some one? Great question. I don't think you have to make a great sacrifice but i think you must be aware that you are always already on the line. It's benal a sort of meaningless to claim or offer solidarity when indeed nothing is at stake for you at all. Then it comes back to the idea of charity. But then,  on a certain scale, something is almost always at risk for all of us. You know, in the climate emergency, we are all already on theLine.
