"Foods containing sugar have been found to save lives in a number of studies."
"Regular smoking use is associated with lower BMI, which is shown to correlate with improved heart health and lower mortality rates."
"Use of fossil fuels powers a number of ecology-preserving tasks, allowing us to care for the environment in a way we could not without this amazing source of Earth-loving fuel."
It's fairly easy if you understand the meaning of "can be true". There can be countless instances where it's not true but if you find just _one_ instance where it's true, then your "can be true" statement must be true.
Disproportionate benefit insinuation error: Implying (without explicitly stating that it has more benefits than disadvantages because that would be a disprovable lie) that because something has some benefit, it is overall helpful.
Or just "plausible deniability"- factually stating the existence of a beneficial tree, but omitting mention of the harmful forest
Or just "cherry-picking"
Or to cover cases where a harm is insinuated/emphasized in the same way in order to discredit something (see: literally all the antivax data, antiscience, antimedicine... "trust doctors, you mean like the ones who prescribed thalidomide?")... "Misrepresenting the forest"
