So after some discussion in the comments my own thoughts can be encapsulated as follows:
- In academic circles there is considerable difference in the usage of the terms 'ethics' and 'philosophy', but both terms are used interchangeably here on Veganism & Vegetarianism. My own take on the terms themselves:
- Ethics: a more narrow field that is comprised of a series of moral guidelines.
- Philosophy: a wider field that is comprised of a more overarching set of beliefs.
- These niceties are really not relevant on Veganism & Vegetarianism where realistically a single tag could be effectively used to cover all needs.
I suspect that the better choice would be to merge the narrower field (ethics) into the broader one (philosophy). This would be a merge of the ethics tag into the philosophy tag with or without the formation of a synonym. Details on those choices can be seen here:
What's the difference between merging a tag and creating a synonym?

I have created an example wiki tag excerpt here as well as an example full tag; cannibalizing unashamedly from the existing ethics tag:
Philosophy wiki tag excerpt:
For questions about philosophical, ethical or moral areas relating to veg*n practices. Aim to ask questions that do not invite primarily opinion-based answers.
Philosophy full tag:
Many people follow veg*n diets and/or lifestyles for philosophical, ethical or moral reasons.
This tag should be used for either broader questions about about the overarching philosophy of veg*nism or more narrowly focused questions about the ethics or morality of veg*nism.
For a useful debate on how this site should handle questions about the issue of the philosophy, ethics and morality of veg*nism see this Area 51 post:
Should Ethics be Allowed?
Well, those are my thoughts on the subject, feel free to completely disagree or suggest corrections :)
