(I suppose it is worth pointing out that flattering is perhaps even more secure.)
From Anthony Trollope, The Way We Live Now:
“The ‘Evening Pulpit’ was much given to politics, but held strictly to the motto which it had assumed; — Nullius addictus jurare in verba magistri*— and consequently had at all times the invaluable privilege of abusing what was being done, whether by one side or by the other. A newspaper that wishes to make its fortune should never waste its columns and weary its readers by praising anything. Eulogy is invariably dull, — a fact that Mr Alf had discovered and had utilized.
“Mr Alf had, moreover, discovered another fact. Abuse from those who occasionally praise is considered to be personally offensive, and they who give personal offence will sometimes make the world too hot to hold them. But censure from those who are always finding fault is regarded so much as a matter of course that it ceases to be objectionable. The caricaturist, who draws only caricatures, is held to be justifiable, let him take what liberties he may with a man’s face and person. It is his trade, and his business calls upon him to vilify all that he touches. But were an artist to publish a series of portraits, in which two out of a dozen were made to be hideous, he would certainly make two enemies, if not more. Mr Alf never made enemies, for he praised no one, and, as far as the expression of his newspaper went, was satisfied with nothing.”
