In a community, where skills and expertises range, there always will be people asking different questions, based on their needs.
Hashnode is extremely friendly and welcoming community. The first thing a newcomer see is how everyone who asked a question, gets the proper attention and in-deep answer/solution to his problem. Although the main purpose of this platform is to provoke its users to communicate and discuss opinion and experience based questions, we just can't have only this kind of questions. We can't forbid them too - this will be truly ignorant. As a user of devmag/Hashnode for over a year and a half, there always has been a balanced proportion of bug/error questions and opinion based questions. Hashnode's team is doing an exceptional job of keeping this balance.
Also, a "simple" question for one, can be a show-stopper for another. A user may be looking for an explanatory answer to his specific problem and not a short "use X" type of answer. Different users like to answer different questions and contribute differently. I'm sure there are developers here that would gladly answer bug/error oriented questions.
That being said, I have to agree that if the number of these questions start to rise, we may have a problem. But totally rejecting them seems too harsh. The key word here is balance. Everybody should feel welcomed, no matter the questions one have.
As @sandeep proposed, a better way of handling these questions is the logical and more rational solution to the "problem".
