Mostly people attack or criticize threads without really understanding the context in the content. Before you condemned a thread, you have to understand the "word register", so that it will not affect the OP feelings.

Although not everyone will support the ideas and the experiences of the OP. But still try to find out the  WWW ("Why: The reason of writing, When : The time it happened and What : The degree of the experience") of the OP. So you will not hurt the OP feelings instead he learns more from you.

Someone will write article with his own experience but another person will say it is not true.. That means you are calling him a lier..

And those people that condemn work are getting more merits than the OP himself from his own experience.

There are some people that understand the word register before attacks and Criticize and I like them, I always learn from them.
