You'd be surprised how easy it is for people to compartmentalize their principles. Many do it day to day every time they purchase something online that was probably made using less than ideal labour practices.
Still, I'd advocate to leave social media in general. And certainly to get off twitter.
Hmm, I'd argue what you call "compartmentalize their principles" is in fact, NOT having principles.
Correct me if I'm wrong: I'm asserting that having a principle is an inalienable belief that actually guides behavior, not selectively applies to behavior.
Though generally: yes, I agree: get off twitter, and I'd go a step further and say..minimize all social media involvement.
I agree with your sentiment. But if we go this rigid with it, we might find that the majority of humanity does not have principles.
