Whose anyone to judge someone else on what causes they find emotionally moving? Like everything else about us, what tugs on the heart strings will have been shaped by our own individual experience, whether that means not being able to comprehend or in some cases being all to well able to comprehend and disassociating - it doesn't call for name calling and shaming someone.
I get moved in very different ways by animal and human causes. It's rare a human cause will get tears from me - I get angry and I get practical. Of course I have empathy for the suffering of others, but it's my natural inclination to want to look for a solution to work towards. We're all human, this should be possible, it's what we do. Are tears really a better currency than action?
Animal causes - well yes they do get my tears going. I'm a soft touch and it upsets me to see humans treating another life so cruelly and without reason.
I have pondered on the reasoning behind this before, and I think for me personally I feel that with another person they have a capability for understanding the situation they're in, a chance for hope or peace where as animals don't have this ability. They live in the here and now, all they know is the pain. Granted this is just my own take on it, I'm sure someone has some knowledge that blows a hole in that theory.
Fwiw I have worked/volunteered over the years with young and old people with needs ranging from a bit of support with their shopping to working in a childrens hospice. Yes it is upsetting, but it also is something that needs to be done and something that selfishly gives me a sense of having made a difference. I can do this and do it well (imo) because I'm able to be practical and control my emotions. I need to be the strong one for those around me who can't be, my feelings can be comforted later after the work is done.
I could not work with animals in any capacity. I'm far too emotional about them to be of any use what so ever to the point I'm not really capable of doing what needs to be done. I have my pets, am massively into garden wildlife and will always help out any animal I see in distress to get to where it needs to be, but my emotions still make me unsuitable to be of any practical use in a real situation.
Epic post - but I'm really trying to get across that being upset and crying isn't a reliable indicator of caring.
