You really do need to educate yourself. You say circus animals are the luckiest animals in the world? Okay, so we will take you out of your natural environment, place you in a jail cell, serve you food, allow you to see doctors if health issues become really bad and we'll then say you're the luckiest person in the world.
Oh and if you want to go exercise or socialize with other people, we'll yell at you and hit you because you're not supposed to do that.
I can't believe how ignorant some people STILL ARE even with all the resources available via the internet. It's such a shame.
