Mankind could not exist without Heterosexual Reproduction, but could continue without Homosexuality

MANKIND'S EXISTENCE DEPENDS ON ONLY ONE OF THE FOLLOWING TWO: HETEROSEXUALITY AND HOMOSEXUALITY.  DAMN, I WISH I WOULDN'T COME UP WITH SUCH TOUGH QUESTIONS.  AND AFTER ALL IT'S JUST SO POLITICALLY INCORRECT.  OF COURSE FOR THOSE WHO DON'T LIKE THE TRUTH, THE TRUTH IS CONSIDED HATE SPEECH.  IMAGE BY POLITIFAKE
