Too many people these days say hurtful, even cruel things to others online without knowing all the facts.
The vast majority of the time, you don’t know what that individual may be going through, and in all likelihood, you don’t know the whole story either. Making quick, usually unfair, judgements that you post online is often very painful to the individual being targeted.
Many people are hurting and in pain these days for whole variety of reasons. Don’t add to that pain by prematurely jumping to conclusions and then attacking someone based on that.
Try to be thoughtful and considerate. There is a lot of truth to the old saying that if you don’t have something nice to say to a person, don’t say anything at all.
And remember: most of the time, you don’t know the whole story.
