Veganism/vegan ethics/animal rights seek to end the unfair use of other animals and unnecessary cruelty, when we can do that. I'm sure most of us here agree that when it's not possible or practicable, it's at least acceptable though perhaps regrettable to use or kill animals. I can't imagine any vegan killing large numbers of humans by driving their car, but we accept that all day long for animals. Few vegans would argue that it's OK to kill 20 or 30 itinerant humans on every hectare of croplands, but we accept that for animals every time we buy food at a shop. The bottom line is that animals can be pests, they can be threats, they can be resources and they can be food. And any time we don't have all the benefits of a modern Western society, they are resources and food. I don't see what's wrong with accepting that reality but still advocating to be fair to them when we can do that. We just cannot do it all the time in every context.
As for unpleasant people being nasty towards me because I eat some eggs, that illustrates the fundamental failure of vegan advocacy. For some reason, vegans (like a lot of people, I guess) fall back onto nasty personal insult when their cherished notions are challenged. The eggs I get from my farmer friend are absolutely vegan-friendly, and far more so than many plant-sourced foods most of you buy commercially at a shop. Failing to see that underlines why veganism is so poorly appreciated by most folk.
