Some breeds require ear / tail trimming because they're the result of years of genetic manipulation by humans and are flawed and more prone to infections or injuries, especially if the dog is used in security or fields that imply rough physical contact between the dog and another animal or human being.
I don't think any sane person thinks a dog "looks cooler" with body parts trimmed out. 9 out of 10 times it's done to improve the dog's quality of life unless you're a psycho.
That's why this is done when they're in their growth period, so they hurt less, heal faster and their ears don't just get trimmed the usually get a cask on them like a bandage so they grow upwards. (the idea is not to trim, it's to get to it the basic dog ear design)
Don't like the practice? Stop breeding dogs that are genetically flawed because you think they're cute.
Now, can you stop something humans have been doing since the dawn of time? No. Move on with your life and stop making #sadposts for attention.
