Bigot towards unmarried couples on Judge Judy

On Judge Judy one man labeled his tenant's relationship with a man 'immoral' because they were unmarried.  I think he is wrong for labeling an unmarried couple's relationship as 'immoral'. Judge Judy said some people think that unmarried couples living together is 'wrong'. Well, I think the people who view unmarried couples who live together and have sex together as 'immoral' are wrong.  There is nothing 'wrong' or 'immoral' with unmarried couples living or having sex together.
