You know what a personal choice is?
Painting your room. You’re not hurting anyone, it’s your room, you can do whatever you want with it.
You know what’s not a personal choice?
Eating animals. You’re hurting them! You’re taking their lives for a meal. Animals are not yours to impose your will on. They are their own, and they deserve to live. They do not deserve to be killed for convenience and taste.
Choices aren’t personal when there’s a victim.
