@alex It is a matter of consistency. And though I do hate to be "that person" I do make a point of informing cheese eating vegetarians about rennet.

As a beekeeper, I do feel the need to share my knowledge with vegans. If you concern is the subjugation or enslavement of a species regardless of mistreatment or harm or mutual benefit, then to be right, you should probably restrict your diet to grains and leafy greens avoiding most fruit bearing choices such as melons, cucumbers, tree fruits and tree nuts, and vine fruits. Not to mention cotton and canola. These products are pollinated by bees, and those bees are placed in those environment by beekeepers with managed hives for pay.

Of course, you might also reconsider many of the grains and green leafy vegetables as well unless they are organically farmed, since billions of insects are indiscriminately murdered with chemical warfare.
