The one who sits in a glass house should not throw stones 
If you want to complain about others, you had better have none of the issues you are complaining about.
Problem is that what you find annoying with others is also what annoys us with ourselves. There is one helpful acronym you may want to memorize: P.B.S. Pause – Breathe – Speak. Allow yourself some time to think and reflect upon whether or not a response is needed and what the best response is.
If you want to spare your glass house windows apply some P.B.S. daily. You won’t look like an ignorant fool too.
