Unconventional appearance, music, drugs, communitarian experiments, and sexual liberation were hallmarks of the sixties counterculture, most of whose members were white, middle-class young Americans. To some Americans, these attributes reflected American ideals of free speech, equality, and pursuit of happiness. Other people saw the counterculture as self-indulgent, pointlessly rebellious, unpatriotic, and destructive of America's moral order. Authorities banned the psychedelic drug LSD, restricted political gatherings, and tried to enforce bans on what they considered obscenity in books, music, theatre, and other media. Parents argued with their children and worried about their safety. Some adults accepted elements of the counterculture, while others became estranged from sons and daughters.
