Never argue with an idiot.

I know for a FACT that the above advice is wrong! :mad:

Yes Alex, I will take an explaination for $1000. :excited:

I just ignore them or let them spew out their misinformation when I encounter these people.. I even have friends that are like this.. I found it's easier to nod away until they are done. Ignoring them too much will just cause them to repeat themselves a thousand times until you acknowledge them. I just until someone who pretends to know more gets involved with them and watch heads explode (implode?).

I agree.

There's those know-it-alls who try to feel important if they present themselves as being right all the time--> insecurity.

There's those know-it-alls who are overbearing and try to put their stamp on you i.e. pyschological bullies.

There's those know-it-alls who demonstrate their self-importance because nobody else gives a f&ck about them.

When I come across know-it-alls, I usually give them a tongue in cheek "cool", "OK you win"....
