Paul Ehrlich and the population bomb
Context: Solving the population problem is not going to solve the problems of racism… of sexism… of religious intolerance… of war… of gross economic inequality—But if you don’t solve the population problem, you’re not going to solve any of those problems. Whatever problem you’re interested in, you’re not going to solve it unless you also solve the population problem. Whatever your cause, it’s a lost cause without population control.

Doin' It Again, Parental Advisory: Explicit Lyrics (1990)
Context: Same with religion. Religion is nothing but mind control. Religion is just trying to control your mind, control your thoughts, so they're gonna tell you some things you shouldn't say because they're... sins. And besides telling you things you shouldn't say, religion is gonna suggest some things that you ought to be saying; "Here's something you ought to say first thing when you wake up in the morning; here's something you ought to say just before you go to sleep at night; here's something we always say on the third Wednesday in April after the first full moon in spring at 4 o'clock when the bells ring." Religion is always suggesting things you ought to be saying.
