My preference is to speak the truth, and...if possible, in love :)
(actually, speaking the truth is loving compared to allowing someone to wallow in error).
If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.
1 Corinthians 13:1 ESV
I hear a gong when people start speaking the Truth out of love.
