>is what we do wrong?
No.
>if you're a theist what do you think god makes of you shitting on the weak?
Agnostic. But if there is a God who cared about the human social order, then I'm fairly confident that he'd endorse this.
>do you have a personal philosophy which allows for this?
Outside of man, there is no such thing as right or wrong. Only man is capable of comprehending and formulating moral propositions, and virtually all of them are sourced from a kaleidoscope of nebulous intuitions.
It's only through postulating the existence of a God - which would have us claim that such intuitions are insights into His moral order. If you, like me, cannot accept the theistic claim, then you must acquiesce that the limits of moral and political theory necessitate morality as being constructed.
Does this mean morality is meaningless and it should be an anarchic and hedonistic free for all? Not if you want to win. Nature has endowed most of us with a desire for pleasure, an aversion to pain, and a desire for dominance/mastery over nature and others. More formally, there is a shared conceptual 'arrangement' of meaningful desires and interests of what are the proper ends of human behaviour. Thus, to most of us, there is a qualitative truth that there is a 'better' life than another; since we are 'sane' (ie, share the conceptual arrangement) we would choose the life of Socrates over CWC, and in most cases Socrates dissatisfied over CWC satisfied.
Morality is thus not an arbitrary and meaningless thing without God. Instead, morality is best understood in the way the anthropologists have tried to place it; as a system of low time preference behaviour that generally serves to maximise the long-term fulfillment of the afformentioned ends of well-arranged humans. Once we trade out the categorical imperative of God or of Kant's fantasies and instead see moral thought as being a hypothetical imperative born of the best empirically tested way to satisfy human interests, then we see plainly why it is in truth exceptionally moral to break degenerates, troons, and trogs.
For lolcows and weaklings are conceptually disarranged. They do not share the same interests as the human community; their pleasures and pains are aberrant and/or their mediums of power or dominance is misplaced. But you can't have a rational dialogue with that - the proper ordering of the human conceptual arrangement is ultimately born by psychology, not by the powers of ratiocination.
Thus, our work is best considered more equivocal to that of police or soldiers of the conceptual realm, rather than academics or writers. We patrol the boundaries of sanity and decency, locate aberrant agents, and proceed to break and humiliate them for the collective good. This is necessary, for if aberrant thought becomes the norm, moral precepts are questioned, and the conceptual arrangement is challenged and the traditional path of human psychological development is undermined, then the system collapses.
In an age where it is (falsely) believed that all problems may be dealt with through dialogue, and where tolerance is threatening to undermine the psychocultural order itself, our work is all the more necessary.
