classjacking 

When a class discussion is hijacked by a rambling, tangential and eventually irrelevant but wholly derailing observation, grievance or out-and-out rant by one of the class participants.

We were in our final session on behavioral economics and this woman started classjacking the discussion into the moral underpinnings and motivations of the study of economics, behavioral or otherwise.

classjacking 

the act of a class co-opting an existing oppressed class’ cause, culture and terminology to advance its own agenda

A real life example of classjacking would be the trans movement pretending to be an ally of gay rights and co-opting the social justice language deceptively.
