"This is definitely a good thing to care about. I never necessarily thought of blue ones as being gendered, I just set up teacher-student scenes to have 3 blue creatures and 1 brown creatures to match the channel name. Perhaps the same goal can be reached just by referring to one of the students or to the teacher... |
