I saw reintroduce the natural predators.

There is a value to that and it does seem to have a positive effect on the environment. Check out wolves and Yellowstone park as a case study. That said, it's also important to note that just like the deer population would need to be kept in check, so would any predator population. States in the midwest (where deer are a problem) are not like Yellowstone in Wyoming. There are many more urban areas and a much denser human population. Public safety is a huge factor and having sensationalist articles about how a pack of wolves have torn up the some familiy's beloved dog will only hurt their image, not help.

If we hadn't already meddled, we wouldn't feel the need.

Well we did meddle. Now deer are a problem. Now we're meddling more to fix it. Hunting helps. Not only does hunting help to control the deer population, but the money raised from hunting also helps to fund conservation.

I don't believe they are the problem we've all been led to believe.

Okay, well, you're probably wrong. Sorry.

There are cheap devices we can put on each and every car that scare deer away.

They arguably don't work. Sorry.
