Abortions and homosexuality increased the size of the federal government?
Sure. The need to keep Social Security solvent by adding replacement workers to fill the baby bust has been a prime mover in illegal immigration. Abetting homosexuality adds child abuse cases, crime, adds to the number of broken families in need of welfare, increases the number of single parents whose kids are less productive than otherwise...
There evokes the reason communist Antonio Gramsci advocated immorality, feminism, and homosexuality in his program of Cultural Marxism: It was to break down the family as the foundation of Western Culture such that the state could take the lead in child rearing. Gramsci's heirs in the Frankfurt School were kicked out of Germany in the 1930s and came to Roosevelt's America. Adorno, Marcuse, Fromm, and Maslow were instrumental in imbedding Critical Theory into the American academy. The rest is history.
