Kant's categorical imperative is a ridiculous concept
Oh foolish boy...
Your objection is that the categorical imperative necessitates a perception of equality, one that people often lack? So it is ridiculous because it is idealistic? You pointed out that people don't behave in this manner, but you haven't said much about if they should or not.
It is true that an individual’s subjective beliefs will color what they would think objective conduct would be, but it also inherently causes a person to stop making exceptions for themselves. While this might not obtain true objectivity, it decreases our subjective favor towards ourselves, allowing us to move away from what is right for us and towards what is right.
The family unit couldn't exist as we know it if we lived like other animals.
Actually the human response to visual cues of infancy (large heads, big eyes, gurgling noises, etc) is so over-the-top that not only are we biologically motivated to protect our own children, not only are we motivated to protect other human children, we are also motivated to protect a lot of cute cuddle animals as well. Family units still exist quite nicely even though we like our pets. Or perhaps you meant
like-like?
... and social bonding sometimes
- oh and its fun.
The release of oxytocin is part of the chemical cocktail of orgasm. Oxytocin is a necessary part of forming social bonds and trust (if your body doesn’t produce or process it correctly, you can be prevented from forming social relationships). Sex is always about social bonding, then. We might not want it to be, but meh, too bad. That is the way our bodies respond to the stimuli. Though, to be fair, oxytocin effects and release vary by individual, so for some it is more socially bonding than for others. And of course, just because we have some chemicals swimming around in our blood, that doesn’t mean we are bound to them.
Did you get that off a Christian website? I wouldn't be surprised if so. I don't know why christianity has so many followers when one of its own beliefs is to objectify women...
Probably because that isn't one of its central tenants. Look at the Nicean Creed; most Christians hold that to be central (most, not all). You may note the lack of woman-hating in its contents. Like palliums and bishops, objectifying women is one of those time honored traditions that got added later, that many people still follow, but is not a necessary part of the faith.
It is true that the bible isn't particularly nice towards women. Even if it has absolutely no spiritual merit, it is still a historical document. Thus, having been written during periods in which women were not well respected, one should expect a significant lack of respect. Your objection, then, is essentially that the bible is old.
Did you ever notice that, oh I don't know... that we're the only species who endorse religion, and the most violent? Yes, animals can be violent, but they don't possess WMDs. Even our predecessors, Neanderthals, had no religion.
Who said Neanderthals had no religion? Honestly, I can't recall ever having heard "Neanderthal" and "religion" in the same discussion, so I would be quite curious to learn more.
Also, how does WMD make us more violent than others? In increases our capabilities for destruction, true, but how does it relate to our desire for that destruction. Give a penguin a nuke and make it understand what it is and you might find those happy feet dancing on our graves. Or not. But the tools we use speaks of our ability to make tools, not to the degree of our inclinations.
Ironic how we're considered the most intelligent species, but because someone thousands of years ago got bit in the ass by the stupid bug and decided "Hey, I got an idea! Let's personify natural occurance and worship it!" that we have a more restrictive social order than any animal.
Bees and ants have a far more restrictive social order than any humans have for the simple reason that their social order is reinforced by their biology.
Then there are those species that eat their partners after sex. Mmm, that's some good social justice, I tell you what.
The problem with using animals as a reference point for humans is that we've all evolved differently. Dogs are loyal because of their evolved social behaviors that humans have tapped into and modified. A crocodile might make a good pet until it is hungry, because they never evolved the same social behaviors that dogs did. And if a human acted in either way, we would (or should be) horrified. Why? Because humans have social behaviors, but they still aren't as well developed as those of a dog. Humans like dogs, but humans are not like dogs. Good, bad, we're the ones with the gun. We can’t look to animals to figure out how we should use it.
