That's an empirical premise in a slippery slope style argument. Any evidence to back it up? Who is opposing the terms allow/deny and why? I don't see it.

The terms allow/deny are more directly descriptive and less contested which I see as a clear win-win change, so I've shifted to use those terms. No biggie and I don't feel self-censored by doing so.
