I didn't downvote, but I read a TL;DR, especially one directed at the commenter, as saying "my time is more important than yours; could you spend your time purely for my benefit, despite my not being willing to put in my time to read what you've said?" All else aside, it probably takes longer to ask for, and then complain about downvotes on, the request than it does to read 4 short paragraphs.

Since when TL;DR's have an obligatory hidden meaning? You can speculate on that, but it's. just your speculation and nothing more and it can be at the compete opposite side of my intentions. So don't tell me what you read in my two words "TL;DR".

There is no way I should justify a request for summary in the first place I just did that afterwards in order to undetstand reasons for downvoting and if that was that someone else is giving their own interpretation to my request, then it's not a valid reason for me.

Their downvote does not make me learn anything new and I just observe how obtuse and flawed their mental process was. They were probably angry for having to read all the long comment I referred to and for not accepting someone else could get away with a shorter version of it. It's called envy and it sucks.

TL;DR:

I don't give a shit about your downvotes if you give your own interpretation to my request in order to support your envy for the fact that I could get away with a shorter version of the original text.
