Well i see it this way.
Freek flipped out on him for saying late withing listening to the explanation for it being late or his apology for what he said.
And Derontchi sounded like a richard saying it was late.
You go on your favourite forum to let other people know about something you found on the internet, something you think is quite interesting/funny and you're relatively well invested in it. You make a thread to expose your peers to this thing that you like and what's the first reply you get?
"late".
You're told that it doesn't matter if it's funny or if it's interesting; you're told that none of that matters simply because it's not recent and it's implied that you've done something wrong that is worthy of ridicule and insult, your very intention of discussing something with your peers is thrown out the window by the very first person who posts in your thread.
I think it's perfectly reasonable to get pissed off in such a situation, to any degree in fact, so long as you don't make yourself look like a complete tool or violate any rules.
