Computing is neither a professional discipline nor a boys club. Historically, it's been a sausage fest, and computing will never be a professional discipline so long as there are people out there willing to write PHP for fifteen dollars an hour and engineers are put out to pasture at 35.
Aside from the fact that PHP, while I personally would never use it, can and has been used to write scalable software, computing is more than just a few poor coders.
It's a bit like saying that being a doctor can't be considered a profession because there are homeopaths. Your argument is neither convincing or logical.
There's nothing wrong with PHP as a language, but I've never seen people offering to write python for fifteen dollars an hour.
And it's not like saying that doctors aren't a profession because there are homeopaths, because homeopaths aren't doctors. The segment of our industry that is more EE than CS is highly professional, somewhat organized, and relatively mature for an industry only fifty years old, but they are a small, nonvocal segment of our industry and they tend to distance themselves from the people who call themselves "developers."
Don't burst a vein arguing over the definition of a profession.
The litmus test is whether or not an occupation has a policing organisation who dictates who is allowed to practice it. Lawyers, doctors, civil engineers are professions. Homeopathers, developers and ditch diggers are not.
