Disagree. I'm vegan and anti-hunting, but I don't think states should be able to enforce their laws outside of their states. That would lead to some real crazy stuff.
Any sort of cross border crime is regulated by the feds. Like if you steal a car and drive across the state border, it becomes a state offense. The feds could make cross border hunting illegal as well, but they would have to put in resources to enforce it.
I was also vegan for years, but not anti-hunting. While not a vegan today, my meat consumption is down by ~98% from childhood. Why are you anti-hunting? Usually, hunters are strong environmentalists. Plus, they are taking animals from their natural habit, instead of crowded feed lots.
I haven’t found it to be the case that hunters are environmentalists except for some post hoc rationalization. It really just reduces to a hobby of killing animals at least with anyone I ever hunted with in my teens. And they were all right wing Texans, definitely not anyone who would sign on as an “environmentalist” except when in cases where they can glamorize their hobby.
