Ethical vegans: Would you agree to go to a restaurant with people who will buy non-vegan food?

[Seryph]

I take it you also only use electricity from renewable sources (including at work and school as well as at home), don't use any plastics at all, only wear clothes that are fair trade and aren't made in sweatshops, don't use cars, motorbikes, scooters, or public transport that uses diesel or petrol, that you only buy books that are printed on responsibly farmed wood, and that all your food is grown locally, organically and picked by you or at least bought at the farmhouse by you after it has been hand picked? Oh and don't forget that the farmer can't use any mechanical field clearing or plowing devices since those will kill any field animals.
I expect the whole of your house and all your belongings are fair trade and none of them are made using anything that could damage the environment or local ecosystems? On top of that they will all be made locally, because again you don't want to pollute the environment by having things transported?

This is the problem with being "ethical" unless you take it to the absolute extremes, you are being a little hypocritical to develop "a strong aversion" to other people. Especially since they may actually do more of the things I listed above than you and thus could be considered more "ethical" than you.
