Thanks Kristina, Like you, I can't understand hateful comments. Personally I haven't experienced any as yet, but even one would probably derail me.
I think the problem may be that super-confident people just don't 'get' why a person is hurt be being called a name. I have no ideas about how one might turn that around, but at the end of the day, the writer is just a name on the page, someone you will probably never meet in person, so time is the product that can help recover, the healer if you like. If someone bad-mouths, just allow the hurt in, but don't respond. In time you wont even recall who the writer was.
