replying to someones question doesnt mean that you have given them a the best solution to their problem or right answer to their query
It may be better to have a wide range of replies to consider...people look at things from a range of angles and see things differently from each other.
So NO, in my opinion people who keep asking are not "Jerks" and I doubt they are "slow" either.
calling people "jerks" for perhaps not accepting YOUR take on things is rather childish...and offensive in my humblist of opinions
