Famous quotes containing the word expression:
“Feminism is hated because women are hated. Anti-feminism is a direct expression of misogyny; it is the political defense of women hating.”
—Andrea Dworkin (b. 1946)
“While I shall not vote for the prohibition amendment, I would like to see a good, wholesome expression of temperance sentiment.... Personally I do not resort to force—not even the force of law—to advance moral reforms. I prefer education, argument, persuasion, and above all the influence of example—of fashion.”
—Rutherford Birchard Hayes (1822–1893)
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
