Didn't have to look far. But really this is a commonplace occurence.
Most of the OSM world isn't TIGER, and doubting one's edits (including
but not limited to deletions) is a healthy quality-assurance reflex.

If I'm following things right, the claim was :

I'm sure nobody will disagree that we have a lot of bad data (in
absolute numbers, not in percentage :p), and it's silly to think that
TIGER is the only source of it, or even that all TIGER data is bad.

In that context, arguing that deletions are intrinsincly a bad thing
does harm OSM's QA process. Clearly we should think twice before
deleting something and don't want to reach an extreme of "if in doubt,
delete", but what you've proposed is the opposite extreme and is just
as unhealthy.

For what it's worth, the only place I've felt disempowered in OSM
(appart from the lack of free time) is the very high bar set for
automated edits. Wether that disempowerment has resulted in a net
positive or negative for OSM is left as an exercise to the reader.
