Thus, nasty responses to a negative post, say more about the poster of the response, than anything else.
When I post, I know there is a person on the other end. I am not a monkey.
I reread what I intend to post imagining a person will read it.
I occasionally revise it to tone it down before sending it.
Sometimes I mess up and I am impolite. I try to apologize. I also try to reflect.
Nothing above seems beyond the ability of a normal adult.
For those who think these steps are too hard for them, the question becomes, What has gone wrong in your life?
