I would never say that a non-christian can’t be loving and caring. My comments, specifically, were directed to people who claim to be Christians yet disregard the teaching of Jesus.

Anyone’s motivations to be loving is based on their beliefs. As you state, you believe “it makes sense to help others.” You believe “[t]he world could use more kindness.” So, that is your belief, and I have no problem believing it may make you a better person than me. The larger question, as I see it, is: Can you be loving and disregard truth? And I would say No, you can not, not ultimately. If you miss the ultimate point of life then… well, just that — you miss the point.

I would agree with you to an extent: If your belief that we being kind makes sense inspires you to be more ‘loving’ or kind, fine. There are larger questions, though, of whether your belief is enough, and whether it even makes sense.
