Mugging has nothing to do with sex. It is a white invention, in old Chicago days called "strongarming." The technique is for a man or woman--it is operated by both--to come up behind a man or a woman and throw an arm around the front of the throat, closing it sharply, with the elbow out. This gives an immediate condition of semi-helplessness and the defense against it is difficult because both hands are not as strong as one arm. At the same time, the mugger shoves a knee into the small of the back of the victim, further devitalizing him or her and throwing off any balance which might permit of a struggle. By this time one or more co-workers are going through the handbag or the pockets. Often those selected by such criminals are persons who have been seen in saloons or elsewhere with valuables or sums of money worth the effort. In not a few cases, where victims have put up a struggle, they were stabbed or choked to death. The comparatively high-class Negro cafés with entertainment which flourished during Prohibition were put out of business by a number of concurrent consequences. The kindly, grinning, amiable and frequently obsequious Negro was disappearing. In his place came a truculent, class-conscious, race-conscious and union-conscious, embittered man or woman, resenting whites and demanding white wages. The early clubs, with their all-night white carriage trade, their quick and friendly waiters and their low-comedy performers had to fold. Negroes working for a white employer demanded white men's pay. Negro workers insulted white patrons. The new trend decried Negroes stooping to low comedy--the calling was for dignity; no more thick red lips or prop watermelons or plantation togs. Why shouldn't they sing grand opera? Why shouldn't they play Shakespeare? They have done both, with here and there some success, often overestimated by "tolerant" critics, but there is no more Negro theatre and there is practically no Negro entertainment as it was known so long, a native American institution. The minstrel show, which was at one time tops in popularity on our stages, was wiped out forever, far ahead of the Uncle Tom shows, which the CIO and the societies for the advancement of colored people picketed out of existence. There are three good-sized night clubs in Harlem now. They play to very few whites, except those who regularly "mix." It may surprise many of our readers to know that in the constantly growing mingling of whites and Negroes, white women with black men are far more numerous than white men with black women. The Harlem community accepts--though it despises--these Caucasians who cross the color line, or as it is known above 110th Street, "change their luck" or "deal in coal." It is common knowledge that girls and women associated with night life to a certain degree have long crossed the line. These are usually dope addicts. That does not mean that many of them are not fresh and young and desirable.
