Truth is only a weapon for the Father of Lies and his coterie. Truth is the 'oxygen' of Catholicism and Christianity. It does not hurt people (as bombs or other weapons do), it frees us. It is to falsity what light is to darkness. "I am the Truth" - the Prince of Peace.
Speak and Live the Truth because One Day you will have to give an Account to God Almighty on what you Knew!
