[Chaerophon]

So the bigotry you accuse me of is just your abstract creation - you dont believe its build with logical foundation on any base which humans generally agree on.

Actually, you misunderstand me completely. Morality is not an absolute - it is not a derivation of correspondent truths. Morality is a human construct - as you point out - and while it must have a logical basis, or in other words be created out of the interaction of 'sound reasons', that any particular moral code meets any test of logic does not necessarily ensure that it is 'correct'. There is no test of 'logic' from which one can derive 'the perfect moral code'. Moreover, not all moralities stem from abstract logical foundations, although any morality must be logically coherent and articulatable in the language of public discourse for it to be legitimate in a society such as ours.

Logic is the tool that we use to dispute different conceptions of moral truth; it is not its abstract source.

You appear to contend that there is one unified order recognizable to us through the use of reason alone. I contend that meaning and order are human constructs that legitimate themselves in the public realm through logical coherence and the contestation of logical/reasoned discussion. In other words: you believe in abstract truth, and I do not. I believe that truth can be constructed, but never abstractly 'identified'.

But all of that is a ways away from the horse bit...

To be more specific: there probably is a way to make a logical argument that domestication is slavery, and you know it.
