Earlier quoted context omitted.
Agree. It's endemic of the political and cultural climate we're in right now, where mob rule is becoming the status quo. Personal politics should be just that, personal.
Politics by definition cannot be personal. It's the practice of resolving conflict within society; if you don't interact with society, there is no politics possible. (Note: this doesn't mean I agree with the behaviour shown in this case - nobody says politics between colleagues must be done over Twitter.) (edit: sad downvotes without actual logical counterpoint are sad.)
(human) politics requires just 2 people, not a whole societies’ worth; even zero people at the limit, since politics happens in and with other species too.
