Crazy to think TWRA allowed spikes to be killed on WMA's "managed" for bigger deer.
Believe it or not, this is not necessarily as bad as it may sound to you.
In most cases, managing for larger antlered bucks also means maintaining the deer density below a certain threshold, so that there is more deer food per deer. Better nutrition means bucks' antlers "express" more of their genetic potential, and do so at younger ages.
In trying to reduce deer numbers, one of the "fears" is accidently shooting a button or spike buck, mistaken for a doe. Making spike bucks legal allows for a higher doe harvest, while not overly punishing a hunter for accidentally shooting a spike. This is also why "button" bucks are commonly counted as "antlerless" rather than as antlered bucks.
Lastly, just a fact, most spike bucks, are about a year behind in antler development until they reach 4 1/2 or older. Then,
some spike bucks are indeed genetically inferior regarding antlers. So among the yearling buck cohort, it is spike bucks being killed that do the least damage to a "trophy" buck management program.
The bucks most needing to be protected are the 2 1/2 & 3 1/2's with superior antler genetics. But good luck finding any regulatory method of protecting those particular bucks. In fact, most antler restrictions actually contribute to higher harvests of the best antler genetics (as compared to no antler restrictions at all).
