Well ... not always. :-) I recall Our Lord calling the Pharisees "whited sepulchres" and telling them they were "true children of their father, the Devil".
Sometimes the truth does not sound "loving and kind" ... but which is more loving, to tell the harsh truth, or to sugar-coat it?
If I am not mistaken, He has called us to love each other.
The fathers record that St. John the Apostle, when he was a very old man and had to be carried to church because he couldn't walk, preached just one message: "Little children, love one another. It is the Lord's command, and if you do it, that is enough."
But, by the same token, telling falsehoods about one other is not an act of love, and righteous anger when falsehoods are being repeated is not necessarily the wrong reaction.
My point is this. Let's heal the breach not fan the flames. Protestants and Catholics have many misconceptions about each other, but the devout from each group are incredibly alike in their devotion to Him. I don't think any true believer would want to spread a lie but we all make mistakes. Let's help each other see the light...let's gently point out each others errors.
You would be hard pressed to make more mistakes than me, so don't think I am criticizing you. Anyway, for what its worth...
