yesterday you were setting a boundary against something that made you uncomfortable, you were not arguing at all.. that was justified. other than that its true that you constantly give attention and respond to weirdos or trolls online, that you should block. for the sake of enjoying your experience online and for your mental health too. its always ok to block for any reason (esp on twt). you dont have to take a break from twt, just change the ways you interact with it.
