I'll be honest, I assumed most people reading would be capable of seeing the nuance (and judging by the likes, I know at least some people did, so my point wasn't so badly made as to go over everyone's head).
When you accuse someone of not helping people because they help primarily women and children, it's unlikely that you are suggesting that women and children are not members of the Homo sapiens species (although if you are arguing that men can be women, you don't know much about Homo sapiens so I wouldn't be too certain). You are, however, suggesting that "people" possess an inherent nature, humanity perhaps, that gives them value. And whether you meant to or not, you've let slip that on some level, you do not think women and children possess this value. They are not included in what you meant by "people" when you so valiantly and heroically called for help for people.
Hence why I told that poster that I was sure they didn't mean to imply that women and children aren't people, with all the inherent value that carries, but they had, and so perhaps it was time to do some mental recalibration. (And I know they didn't mention names but if you believe they weren't thinking of JKR, you'll believe anything).
So I hope that clears it up for you. If it doesn't, I cannot simplify it any further and given most people seem to have got it, I'm wary about why you need so much extra time for it.
ETA: JKR isn't helping anyone? She's helping women and children. Do you want to go round again?
