No, the grievances against Agile are just too voluminous and wide-spread, consider even Dave Thomas's presentation about how Agile is dead due to the ease with which it is subverted for political manipulation [0].
If someone as key to software productivity as Dave Thomas is saying this, it's clearly not just because of a vocal minority.
Your suggestion that we should check whether it's just a vocal minority is a good one. We should check that.
Unfortunately, it's extremely obvious that it's not the case, and the dysfunction / failure mode of Agile is extremely common, by far the majority of Agile implementations.
