How is the etymology of "Guru" relevant to this discussion?

It is relevant because the parent made a disparaging remark about Indians on Quora, while having a username with a borrowed word from India. I dislike the antipathy shown towards Indians online (and off), and I try to combat it where I can.

There are more civil and polite methods of expressing dissatisfaction than the kind of blanket statement that gurumeditations has resorted to above.
