I feel like its way more waste of an effort to yell at someone about the search function than just answer their question. Its not like you have to click on their post...
Say that again when you've seen the same question asked for the 43,787th time.
It's not so much that it's a pain to answer a simple question; it's that someone already asked a question and got a lot of accumulated facts, bullshit and salty wisdom in return. There's no point in trying to repeat all that and they'll probably learn more be reading the original post anyway.
