"They're are just following their instincts"
Well, if it's my kid, then MY INSTINCT would be to eliminate the dangers to my kids. Why is this so diificult for these people to stomach?
Of course. But such things never go both ways. It's like the folks who push for diversity -- but insist that everyone match their own view of the world. REAL diversity means embracing Nazis, the Klan, Pedophilia, and violent rape. No one embraces those things. Which is to say, no one embraces REAL diversity. The clarion call of diversity is always a smokescreen.
Allowing wild animals to do whatever THEY want, simply because its instinctual, is also a smokescreen.
