(http://chn.ge/1R7F7Nh) Pacquiao, revered in the Philippines for winning world boxing titles in eight different weight classes during his 20-year career, suddenly fell from grace after a 30-second interview on local television about same-sex marriage, which he opposes.
"It's just common sense. Do you see any animals of the same sex mating? Animals are better off, they can distinguish between male and female," Pacquiao told TV5 on Monday.
"Now if men are mating with men and women with women, then they are worse than animals," he said.

Same-sex marriage is not allowed in the Philippines, where more than 80 per cent of the 100 million population is Roman Catholic.
