This is one reason I hate the common labels "vegetarian" and "vegan". People have this twisted "OHH! GOTCHA!" mentality if you're not perfectly consistent. And by that same token, I think it's common be be all-in or none-in. It's not at all uncommon for (especially Americans) to eat meat for every meal every day of the week. Cutting back is a good goal, even if you're still not "veg*"
Just because you don't do something perfectly doesn't mean it's not worth doing at all.
