I am seeing a trend on here, where people dismiss a technology based upon their experience that they cannot use it first try, even though they clearly lack experience or knowledge about the proper usage.

Also people seemingly tend to imply self explanatory at various topics ranging from relatable broadly known experiences to small nieche opinions.

How is that? Since when do people, especially programmers, think they do not need to explain their viewpoint, even though there is not a clear indicator as to why? Stating an opinion without any backup to the claim is just a void call in the wind. Of course i know that user X thinks that Y is his or her opinion. But what good does it do when i can't relate / understand or discuss this opinion?
