I think we should see people for who they are and not just some label that could apply to them, what is some similar advice to this ?

All labels create division, intended or not. There is oneness in all living beings, we know this when we are born, but by the age of 5, we develop our own identity, we see the you & I as separate, the haves & the have nots, & suddenly we have two-ness. Early Eastern religions also taught this.
