TL;DR

There are ways to offer criticism and there are ways to look like an idiot.  Too long, didn't read is the latter.  Can there be anything more juvenile, disrespectful or unintelligent?

In case this is your first time on the internet, posts, articles and  that are considered by some to be too lengthy will earn the appallingly stupid TL;DR.   Yes, some posts are long, but that has no bearing on whether or not the content is relevant, entertaining or true .  TL;DR is perhaps the ultimate in intellectual laziness, for it dismisses a post or article without actually reading it.  

Imagine a person who stands in a movie theater lobby and, when a crowd enters or exits a particularly long film, say Casino or Amadeus*, this person announces to everyone "That film was too long, I didn't watch!"  Or this same person who stands by the cash register at a book store and tells the customers who have just made a purchase, "That book is too long, I didn't read it."

Apart from being extremely annoying, this person is the equivalent of the poster who responds to a written piece with "TD;DR".   Logic would suggest that, unless asked directly, a person who found an entry to be too lengthy, they would silently skip it and go onto something else.  However, the temptation to say something, no matter how inane, proves too strong for some.  So what can someone say, when they have nothing substantive to contribute?   Apparently, all they can muster is TL;DR.   This is somewhat reminiscent of  people who post "first" on message boards, presumably when no other comments have yet been made.  It is childish, meaningless and annoying.

Sometimes, of course, it is perfectly valid to point out that something is too long, but this can only be known if the actual written piece in question were read.   How else could someone know if it was too long, too short or just right unless one knows what is written?    Saying something is too long implies that it was actually read, so the later half of "TL;DR" invalidates the former and thus exposes whoever wrote it as an idiot who pathetically tries to simultaneously denigrate a work they have not read while drawing attention to themselves.   The only alternative is that the fool who responds with TL;DR has actually read the piece but cannot think of any valid critiques, so they resort to the written equivalent of plugging their ears, shutting their eyes and shouting "La la la la".

But we can't all be mature, high minded intellectuals all the time, can we?  In the spirit of both brevity and immaturity, I submit the following response to anyone inept and foolish enough to use TL;DR

 *Unlike many others, I don't regard Amadeus to be very long at all, perhaps because I hold it to be one of the best films ever made.  Everyone is entitled to their own opinion.
