Because they didn't cast the healing spell on me. Infact, in most cases, no one's casting anything healing on me. They just see that my regeneration is lower than my party members (from the same spell) and infer 'Oh. UR A HOMUNCULI!" immediately from that.

Which is dumb. And metagaming. It's taking out-of-character information (Health healed), and immediately conflating that to one of three races (because they can see I don't have a parasite via double clicking me).
