It's really simple. The question shouldn't be "How much did this particular product contribute to suffering?" or "How much money did so-and-so make from selling this product?", but "Does it involve animal cruelty?" Yes? Then No!
Well, I've put a lot of thought into this over the years and I totally agree that the 'animals don't need your excuses'. What they need is advocacy. I think the question we need to constantly be asking ourselves (following ALL other questions) should be: "Will this decision HELP animals?"
Cast your self-will issues, laziness and convenience factors aside -- that's beside the point.
When you frame your decisions in this light you'll see that things aren't always black-and-white, particularly when advocacy is involved (and you are acting as an ambassadors for animals in the presence of non-vegetarians). Sure, a minute byproduct might have animal origin, but you can bet your life that he or she wasn't raised and killed for it. There are two 'risk' factors to consider in this case:
Risk 1) the risk that your consumption of the minute byproduct in this one instance may lead to your perceived endorsement of animal cruelty by willingly increasing demand of the byproduct to a greater extent than the demand for which the animal was actually killed (which we can assume for the most part was for their meat/skin).
Risk 2) the risk that your present company of non-vegetarians who do not yet understand the value in veganism will be left with the impression that regardless of the ethical reasons for being vegan, attempting to avoid meat, dairy and eggs in their diet is a difficult and complicated thing to do.
IMHO these are the very real risks we are dealing with when we make the decision about how much of a 'fuss' we make about micro-ingredients in front of others. What you do in your own kitchen, or at the supermarket, on the other hand, is a completely personal matter -- you can grow all your own veggies if you want to ensure that no birds, insects or rodents were maimed in the process of farming your food if you like (I try to grow as much of my food as I can incidentally). But to what degree you can be vigilant is really not the question here. It's how to be most effective as an advocate, and how to bring about the greatest amount of positive change toward ending animal cruelty.
To that end, 1000 'not hardcore' vegans will be massively more effective in impacting the bottom line of cruel animal industries by striking hard at the root of the problem and the reason for the existence of these industries: the consumption of meat, dairy and eggs, than will 10 feel-good 'hardcore' vegans. The volume and commercial value of products that the 1000 group can remove from the economic cycle of cruelty will be roughly 100 times greater.
When those 1000 'not hardcore' vegans become 10,000,000 'not hardcore' vegans, the industries that underpin the sale of animal-derived byproducts will be in a state of collapse. They simply won't exist in foods anymore. However, when those 10 'hardcore' vegans become 100,000, the meat industry is still thriving and abstaining from animal products is perceived to be still difficult and complicated and most people are still of the opinion that helping to create change for animals by altering their diet is too difficult a thing to bother to do...
