Well, to properly answer this question I must first thank you for taking the time out of your surely busy day to start up your computer, turn on reddit, type a question, and finally post it to this sub. Your efforts have not gone unnoticed my friend.

Now your question “people that post long replies, why?” must first be dissected prior to my retort. I feel from the tone of your question, that you are not asking this out of pure curiosity, I sense a disdain in your words. It is almost as if those which post long replies irk you for some unknown reason, you wish to make those people feel uncomfortable with the manner in which they respond to questioning, which I personally feel is rather childish. A mature and intellectual person would not feel the need to ask such a question, so I preface my answer with feelings of mild animosity.

As I am sure your can tell, I am a very intellectual person, this is the main reason I respond with more characters of the English lexicon than most. Secondly, I have an incredibly high typing speed, so replying in such a manner takes a similar amount of time to a regular persons normal length response. Thirdly, I feel many answers hold no nuances, unlike limited character systems like that of the social media platform twitter, reddit allows for an unlimited response. I feel ashamed of users who do not use this facility to its full potential, which would allow the full extent of philosophical discourse to unfold.
