You say you know it is harsh—that's already a reason not to do it here. Maybe "harsh" can do some good when there's already a strong relational connection with the other person. (Emphasis on maybe, because people who take harsh stances generally are paying more attention to their own ideas than to the person they're commenting on—but no doubt it does happen sometimes.) Here, however, you're broadcasting to thousands of people over the internet, with zero relational connection. In such a context, it's merely provocative and destructive, and one could even say selfish.
