Many people obliged, accusing the 30-year-old of being hypocritical, given her love of show jumping.

"I don't mean to be disrespectful but [riding] show horses is also animal cruelty," one follower noted.

Others accused her of putting the gorilla's life above that of the child's.

"As a fellow animal advocate I'm disappointed you would post that without researching the situation and gorilla behavioral science," another person responded. "Harambe was extremely agitated and while would not hurt the kid intentionally, may have killed him in a show of intimidation to the screaming crowd. Tranquillizers would not have worked fast enough and if they did, Harambe could have drowned in the water and may have fallen on the kid, drowning both of them. I totally support your animal advocacy and love watching your riding career unfold but do your research before publishing unfounded comments such as this."
