Janet Museveni, First Lady of Uganda, dropped this logic recently:
Uganda’s First Lady has said if cows can’t be gay, then humans can definitely not be gay.
The bizarre statement was uttered during a speech Janet Museveni made while congratulating the Church of Uganda’s bishops for their recent work.
Uganda recently made law the Anti-Homosexuality Act, punishing gay sex with up to life in prison.
[…]
‘We must listen to God and obey him,’ she said. ‘Thank you God for leading us.’
She said the Anti-Homosexuality Act was passed because they owed it to God.
‘If cows did not practice homosexuality, how could we the human beings start arguing over homosexuality?’
Of course, homosexuality has been observed in most mammals, including cows. Janet Museveni apparently needs to get out more often and meet some different cows.
