I respectfully disagree. We write ‘words’, not ‘just words’, sometimes powerful words that affect PEOPLE, whether you will ever meet them or not, they matter, they hurt, they cry, they laugh. They are real. We are no less obligated (perhaps poor choice of word) to treat people we will never meet with respect than we are our neighbour or colleague.
Not everyone will like our words, they don’t need to. We may offend, though we don’t intend to. I don’t think we can completely disregard how we have made someone feel, intentional or not. And I’m not talking about trolls, I’m talking about people who disagree or feel offended. I see no point in responding to or giving trolls any more energy than my finger on the block button.
