Scientists actually had to do a SCIENTIFIC STUDY and PUBLISH A PAPER in a highly respected peer-reviewed scientific journal (PLOS One) to prove that same-sex marriages have NO EFFECT on opposite-sex marriages. Like, the debate has got to the point where scientists had to be like okay FINE do you guys really need SCIENTIFIC FACT that who SOMEONE ELSE marries has ZERO effect on who YOU marry fine FINE HERE IT IS.
Their quoted conclusion (drumroll please): “We conclude that there is no relationship between implementation
of same sex marriage or strong or weak same sex union laws
and rates of opposite sex marriage.”
DUN DUN DUNNNNN
