So what you are saying is, one mistake makes him dishonourable or non-legit person?
We all make mistakes, I am not defending him as I can't be sure if he may have planned this with bad intentions, but what you are saying is a bit over the top or is there more to this?
Next time you call someone poor make sure you say why he is poor as there are quite a few people who are read this, is his reputation that bad?
Has there been more then one mistake?
Quite a few "mistakes" actually
