Eejit, to question things you don't understand, is a good thing, to criticise things you don't understand is not.
Some people on here may be a long way away from close friends and their families and need support. I have read of people annonymously discussing their feelings and experiences of abuse, miscarriage and other personal problems, in a forum where they feel safe to do so. Why deny them the comfort of being able to offload and share those feelings??
I have also read interesting debates on current issues affecting society, where people respectfully share opinions and broaden their understanding and outlook on life. This can only be a good thing.
And finally, I myself have asked for practical, everyday solutions to challenges such as car problems and plumbing, and was grateful not to have to waste money before accessing a wealth of knowledge here.
So fcuk you.
