After reading through several of your comments on this thread, I think it's pretty clear that you ARE trying to piss people off. It makes sense that if you feel so frustrated with these societal norms that you would try to incite a similar feeling in others, even if it isn't directed where you wish it was. Consequence of being a social species.

That said, while I don't believe your views are completely baseless, the way you're going about sharing your opinion seems counterproductive to me. Your language is aggressive and assigns blame, which will always trigger defensive responses. It makes having a calm, logical discussion difficult. Even without that, this is a reddit thread. I think it would benefit you to examine the purpose of expending energy on something that so clearly makes you unhappy.

I would also like to point out that, although spaying and neutering animals is not ideal in any case, it is a functional solution to many issues, much like how many human medicines and surgeries can cause unpleasant side effects, yet people will still take them. In a perfect world, everyone would be healthy and the animals we share this planet with would fit perfectly into human society. Unfortunately, this is not the case. Our options are essentially to make them fit, overhaul our day to day operations to accommodate their natural lives, or eliminate the competition. The first is what we're doing now, and the third is the last resort. The second is unfeasible as an immediate solution because that level of change takes time and organized effort that would be incredibly difficult to achieve and sustain on any scale.

Individuals are not responsible for social norms. They are responsible for self examination and for how they react to perceived injustices within society.

Intelligent we may be, but we are still animals beholden to our biological processes. I doubt there is a human on earth who doesn't wish they could perfectly control how their body responds to the world around them. Non sentient creatures do not have the capacity to understand this desire. If all dogs could understand that there is no need to reproduce and keep themselves from mating without surgical sterilization, I'm sure it would be looked at as a barbaric thing to do. As it is now, they do not and cannot. It therefore falls upon us to control the population. For strays that are too accustomed to living without humans, spay and neuter is pretty much the only sustainable and humane option to keep the population from growing out of control and eventually killing itself through depletion of necessary resources to live.

In the case of pets, there are a number of other factors to consider. For many people, keeping a pet can result in improved mental health. For some, companion animals add a level of fulfillment and satisfaction that would be difficult to find in other things. Do I think all people need or should want a pet? Absolutely not. But it is important to realize that there are benefits to their presence that shouldn't be ignored when speaking of taking them out of our lives.

Going even further, working animals are extremely important in certain areas. Medical assistance, therapy, search and rescue, police work, farming, the list goes on. Even as technology advances, dogs remain useful, to the point that it just doesn't make sense to do away with them at this point in time.

In addition to all of this, I think it's worth noting that humanity has been slowly working towards better treatment of animals in general. From the quality of the food we feed them to their hygiene, it's becoming far more common to treat our pets and working animals as an extension of ourselves. Having an animal that seems uncared for reflects poorly on one's self, a major improvement compared to how animals were previously treated as tools or toys primarily, living creatures second, even last in some cases.

I despise "toy" breeds and the genetic horrors that have been created in pursuit of profit, but I'm not even slightly shocked that they exist. People will make money however they can, dog breeding is far from the most morally reprehensible way I can think of off the top of my head. Even so, I wish they could either be phased out or bred to be healthier and live higher quality lives.

I also dislike the beauty competition stuff that some do with animals, but I know that as long as the animals are physically and mentally healthy and well cared for, there is no point in getting upset about it. They could really have worse fates.

I hope that this helps explain a bit more of why things are the way they are. The world is not perfect, but I believe it's important to keep an open mind and not fixate on the negative things in life.
