> As a vegetarian (by ethical choice, not medical necessity), I do my best not to lose sight of the simple fact that I'm the problem here.

This sounds like a contradiction to me. You recognize that meat eating should not happen, so it's a problem, but in the same sentence you're backtracking and calling vegetarianism a problem.

If you accept that eating meat is bad, then you're implicitly calling meat eaters a problem. Unless you consider that everyone, you should indemnify yourself. I would never call someone trying to do the right thing in a sea of those who don't a problem...
