It's not the fact of calling shenanigans; it's the vehemence with which it's being done.

There's an inflection point beyond which "[he] doth protest too much, methinks" becomes at least as parsimonious an explanation, if not moreso.

EDIT: Not to say that's happening here, specifically, but ... gestures around there's definitely some emotionally-driven reaction to this idea, amongst (and probably also behind) some of the criticism.

Nowadays that society is more liberal in its acceptance of nonconforming behavior, referring to addition is one of the most effective ways of getting general acceptance to curtail people's freedom, so it's no wonder that people react with alarm.

The vehemence might be due to the silliness of the idea as well as how it is an outgrowth of cultural attitudes people have towards gamers, not just denial.
