Obviously you don't understand. That is okay, because you don't have to.
What you don't realize is there is choice whether or not, someone answers a silly or foolish question in a forum based public. Not everyone is willing to talk to everyone.
You seem to lose sight of that. Why? Because, your reason for being here is different than theirs.
You are technically outside, in a park, having a conversation, with any number of people at once, yet you don't have to speak over anyone. So, asking some stranger a question shows how willing or open they are to discussing what was asked.
Even, if you don't get an answer- it is something that they are comfortable discussing. Therefore, if I want to talk to that person again or ask something different, then I can figure out what their response will be like- positive or negative.
I'm sorry you don't see that, but it's nothing new for the average person, to comprehend, because their view or concept of life is skewed by something. Usually, it's their own limitations, but I'm not going to speculate to what your view or concept of life is.
I hope you find my explanation of my actions good enough. Since, it was so important for you to know.
Have a great day.
