You mentioned freedom of speech. If there are a few who won’t stop trolling, then you shouldn’t stop writing either. Freedom of speech.
When people write about their personal experiences, those who read gain from it. What would happen if all the others stopped writing like yourself? What good is it doing to the world?
If you’re really not going to write anymore, is there somewhere else that you will?
Fun fact: when I clicked published, Medium gave me a suggested tag “Donald Trump”. Don’t let them Trumps win.
