The problem with all the fair chase arguments is who gets to decide what is fair chase? We have a lot of agreements in this thread regarding thermal, but not everyone.
Hunting is a very personal thing. We all take enjoyment in hunting, but many of us in different ways. Some people just want to kill an animal to put meet in the freezer (that’s me on many hunts). Some people want the biggest animal on the mountain or they are happy going home empty handed. Some people love the process of hunting and killing does not have to happen for them to enjoy themselves (this is also me sometimes). Some people are very disappointed if they don’t fill their tag, to the point that it isn’t fun.
Some people like archery, others rifle, etc. When we start putting restrictions on ourselves based on what we perceive as an ethical means of take, we are just reducing individual freedom. I get restrictions to manage herd size and health so that we can continue to hunt. I get special seasons for folks who want to use primitive technology. I don’t get telling people how to enjoy THEIR hunt.
I see the thermal argument as no different than people complaining about long range shooting, or using too small of a cartridge. I mean, what about rangefinders? Talk about a major boost to success rates for all weapon types, but we are all accustomed to it now so it’s seen as “normal”. In the 90s, some people complained about them being unsportsmanlike as well. It’s none of your business as you can choose not to hunt with those tools unless we are talking specifically restricted primitive weapons seasons designed to limit success.
We should be fighting to keep as much of our hunting privileges as possible, including the tools we use.
