It does because we have the capacity to understand and know that what we are doing is wrong.

Look at it in this way: what's more natural then Cruelty...?

Then the expierements would be completely useless since there would be no accurate baseline from which to draw your results from.

I mean, makeup and shit, yeah, screw testing on animals for that, but as far as medicine for people go, it's the only logical thing to do.

Animals are beings of lower biological order, their life isnt as important as a human life. Would you rather have all the medical drugs tested on humans and have them dead sickened?

Lower biological order? In whose's scale, yours? 

Because if you're talking in strict biological terms, humans are pretty low on the biological scale. We're not macro-producers nor are we on the top of any kind of food chain (as there are animals that hunt humans for food). If you're talking about rational order, then that has nothing to do with any kind of biological measure. 

Also, funny thing regarding humans, we're one of the few species in the biological kingdom that has no biological function for any other species. Kinda like locusts but able to do 2+2 in our brains.

sure because animals can't build weapons and decide how the world has to  work. i really don't think that a horse for example would be less asshole like we humans are if they could do what we can, but they just can't.

that's what so many people forget. they say animals are so much better than humans and why do they say it? because animals are to stupid to do what we do or because they just can't bcause they don't have hands to build what they want.

and what i didn't get till now is why so many veggies have a dog or a cat and they give them meat to eat every day till they die. do they think the cow in the dog food didn't have to live on a farm to grow so someone can kill the cow for the food?

do they think the cow didn't have to suffer but they animals we humans eat have to suffer on the same farm or what?

I like this thread and especially what the OP is saying.

I think harmless testing on animals is okay but if it causes them significant harm it shouldn't be allowed under any circumstances.

Shit yeah, everyone stop feeding your pets meat from now on we'll force all life to be herbivores! In a few million years who knows what we'd have, could be interesting.

Intelligence + dominance+ power+ reason + compassion + advancement, top on food chain (yes, humans can hunt down and kill any animal of any species they want) = humans are most valueable living beings on planet, and are thus superior to animals.

Human arrogance at it's best.

Top of the food chain? What's your definition of food chain? Because for an animal to be at the top of the food chain, it can't have any natural predator. Like Killer Whales are the top predator of the oceans. You're confusing sports hunt with food hunting, which are two different concepts. 

As for intelligence that's the only point in which humans are superior to any other animal species, but why would you add compassion to it? Humans are amongst the least compassionate animal species in the planet. It's scientifically proven that communities of mammals suchs as Dolphins and Canines, inter and intra-species compassion is much higher than in any other animal. 

Again, humans are not the most valuable living being on the planet. Humanity and the entire human species could dissapear from the face of the earth in a instant and the earth and every other species would continue on living.

If anything, the most valuable species in the planet are a throw down between Cyanobacteria and the innumerous species that compose Zooplancton and Fitoplancton, the true macroproducers of the world. If they were to dissapear, all life on earth would die in a matter of weeks, maybe one or two months, as nutrients in the ground would cease to renew, plants would wither and die and animals would follow suit. 

Don't place humanity in a pedestal. We're the most intelligent species that's true (and we missuse the capacities that we have so much, that I doubt that we're even that intelligent) but other than that we contribute almost nothing to the earth per se.
