Did your philosophy on non-human life lead you to choosing to be vegan, or because you were vegan led you to learn about non-human life? I ask, because you can have the same learning of non-human life and still choose to not be vegan. They are not exclusive. (I ask as curiosity not a challenge to you)
I’m not sure I agree. If I were to hire a Personal Trainer and they were in terrible shape I’d be doubtful of their skill. What shape the person is in _shouldnt_ matter for their ability to do the job, but because they haven’t gone through the process themselves I’d have initial doubts about their skills. Your actions say a lot about your values and thoughts.
