What was Roosevelt warning against in these sentences?

I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful. . .

Falsely accusing people of evil practices

Writing too passionately on certain topics

Telling the truth will lead to retaliation

Forgetting that journalism is very powerful
