Have we lost civility and respect on Audio forums?

I think we have.  I have seen many discussion on audio forums and how nasty they can become when you have people disagreeing. Seems like there are a lot more know it alls now. I been in 20 years and I can still learn.  But I also know I know quite a bit. Like cables can enhance the sound and higher end well designed gear can truly be ear candy special.  Is this just on audio forums or the internet period.
