Supporting a coup against him is just as bad as supporting a coup in America or Britain.
No, it isn't. Well, maybe it is "as bad" as supporting a military coup against Richard Nixon in July 1974 would have been.
Which still wouldn't have been an ideal solution. An ouster (= resignation) because of the pressure from the street would be preferable. A military coup is only the lesser of two evils.
The greater evil is a president who's violently rejected by up to 48% of his population and doesn't seem to give a sh!t about it. That's the basic problem... from day one he acted as if he were only the president of the 52% who voted for him and everybody else had ceased to exist the day after the election.
