Does the military coup in Egypt spell doom for the country's democracy?

Now, it is a great thing that the lunatic extremist Mursi is gone, however, the modus operandi by which this was accomplished establishes a troubling precedent.
If it becomes a regular occurence, that an opposition can just employ the military to get rid of an elected government that they disagree with, then this makes an actual and stable democracy operated by civil debate, discussion, and democratic vote impossible.
Will Egypt realise, that this is the first step on the path to destruction, or will the fact, that through this coup they got rid of a likely islamist dictator, delude the Egyptians into thinking that military action is a legitimate option to run a country?
