Sometimes not saying anything is the best answer. You see, silence can never be misquoted. (Source unknown)

Many of us have a rather quick tongue, and we respond quickly at any provocation, sometimes to our shame. Especially when the conversation turns to controversial issues, we would do well to heed the warning from this quote. Keeping our silence may avoid instant embarrassment and will certainly avoid being justly criticized.

Anyone who is never at fault in what they say is perfect, able to keep their whole body in check (James 3:2).
