I've found on most internet forums that in the technical sub-forums, folks are helpful and good.
It's in the "off-topic" forums like this board's "Open Forum" and other boards' open forums that things get carried away. And that's what 'open forums' are for. Politics, religion, relationships, current events, world events, etc. etc.
Have you found this negativity in the 'technical' threads? That would drive me away for sure. But I haven't seen it here.
