This "people with good education asking for a military coup" is blown out of proportion by supporters of PT. Perhaps a few crazies do indeed think that, but most of the ones during the protests were talking about "intervention", due to considered abuse of the institutions by this corrupt government. And even that can be done in a totally legal and according to a due democratic process.

However, what the supporters of PT keep repeating is that "the opposition wants a coup", you included. So you are doing no better than "the other side of the trenches". If you really want to engage in the discussion, you should be prepared to argue with the "best" part of the opposition, instead of just trying to invalidate the whole other side based on a few exceptions.

That's such a silly thing to point out. In every single anti-government protest that happened so far, pro-military groups were the tiniest minority. Look up Datafolha's research about the Paulista protests - even though that research has several problems, it makes it pretty clear that almost everybody there opposed a coup (or "intervention").
