Thankfully, there are limits as to what people can do with their land, especially when those activities encroach upon and affect what people can do on "their" land (including hog farms, gun ranges, etc). Since many people pay taxes to support Missouri state parks, it could be considered the people's land. Sorry you seem to be taking this so personally.
As for snakebites, heatstroke, et. al., it could be argued that anyone could be killed by anything, certainly. But I was under the impression that guns were designed in order to kill in a particularly effective way, so I'm not sure you could put a gun-range and gun-toting bicyclists in the same classification as any of the other, more natural nuisances that might cause health problems (accidentally or intentionally) on the trail.
