Some people don't like to see truths spoken. They prefer to take the easy route and call themself a writer because they are in a group who are all doing the same thing doesn't make it right.

Writing is a craft. They either respect that and work to hone the craft or they choose to put what amounts to rough notes up and call it a masterpiece. Doesn't make it so.

The sad part is that some of them could likely be really good writers if they would do the work that goes with learning a craft.
