Perhaps it’s your phrasing? To use a particularly obnoxious phrasing from Wired Magazine as demonstration of how the tone of feedback can influence how it’s perceived:

Tired: “maybe you should rename X to Y”; lacks an explanation of why, ‘maybe’ is often sneering / condescending in this usage, assumes that proposed solution is correct

Wired: “fyi there’s a copy error on the site: X doesn’t match Z, should it be Y?”; explains the problem, asks if theorized solution is correct, makes proposing a solution optional

The chosen example tone is not intended as a reflection or judgment of you in any regard, but the necessity of this disclaimer supports my point.

Its interesting how we can both infer the opposite from our statements. Your start of "there’s a copy error on the site" would seem to me to be more condescending as it assumes that it is a mistake, whereas I merely suggest that it is.

I don't really mind the downvotes, just pointing out how stupid they are. I just think of them as cowardly anonymous idiots and go about my (otherwise awesome) day.
