What is the "real" consequence here? And is it still straw manning, in a sense, to make judgements based on an incomplete story, and jump to conclusions about someone else being wrong, without the whole story?
I don't know about the yoga class incident, but I don't automatically see the ridiculousness the rest in this sub thread appear to -- it seems pretty reasonable to me for a group of students to check their assumptions about what they're doing when they learn about something related in history. Yes yoga is now a trendy healthy way to stretch and exercise, and how could history have anything to say about stretching, but it does not seem silly to me to wonder out loud if yoga may have originated as a symbol of oppression or death, or of submission to it.
