John Mahoney was gay, look it up, he was living with his partner of 30 years when he died.
I did look it up. Her is the entry on this personal life from wikipedia.
Mahoney rarely spoke publicly about his private life,[6] and died without marrying or having any children.[31] In 2002, he said “I was never very mature in my relationships with women. First sign of conflict, I was gone. Wouldn’t discuss it, because I was afraid it would lead to an argument.” This stemmed from a fear of having an unhappy marriage like the one his parents had, though Mahoney did have “several long-term relationships”.[7] He suffered from colon cancer in the mid-1980s.[32] Mahoney lived in Oak Park, Illinois.[7] He was a Catholic who called Christianity “probably the most important facet of my life” and prayed “Most glorious blessed spirit, I thank you for all the gifts and talents that you’ve given me. Please help me to use all these gifts and talents to their fullest. And please accept this performance as a prayer of praise and thanks to you.” prior to each of his performances. Mahoney would also say prayers upon waking up and before going to sleep daily, and would repeatedly pray “Dear God, please help me to treat everybody – including myself – with love, respect, and dignity.”[33]
