Imagine a pub that's got huge signs on the outside and inside stating exactly what beers they sell, and what price. The staff put these 6ft signs up by the door to help people who kept coming in asking the same questions over and over. One day you walk in, spot the sign but don't bother to read it carefully, and march straight up to the bar and say "What beers do you sell? How much are they mate?", and wonder why the barkeep rolls his eyes at you.
Similar thing.
Like you say, opinions and arseholes, but every single response in this thread has been covered before, and recently too. As I said, if people make an effort but still can't find the answer then by all means start a new thread, and let us know what you searched for and where and we can guide you towards using the search function in a more positive way. Just posting up "What induction kit should I buy?" without bothering to search is borderline rude, IMHO.
