A government agency determining limits on, say, heavy metals in drinking water is materially different than the government making declarations of what ideas are safe and which are not. The degree of subjectivity of such decisions alone should make one wince at the notion let alone how subject any "standard" could be from undue political influence of whatever party is in power moment to moment.
The government trying to set a standard in this case is so unlikely to reduce harm in that opposing the idea on principle should be considered the most reasonable, and less harmful, position.
