Sundae Query

It occurred to me this morning that the fundamental justification for the “Selfie stick” is that you can’t ask someone else to take a photograph of you?

What does this indicate? That we don’t trust anyone we don’t know, the ultimate in Us-Themism, or that we are afraid of anyone we don’t know, also the ultimate in Us-Themism.

It seems that we have pursued the matter of racism/genderism/… so fully that we must treat everyone else as if they don’t exist.

But isn’t that the same thing? Isn’t the ultimate form of discrimination denying everyone else’s existence?
