He has the right to voice an opinion. Your response was unnecessarily rude. Please refrain from such “snarkasm” in future, ok?
Thing is, simply voicing an opinion isn’t terribly constructive either. It’s not an issue of whether this person has the right to or not; it’s an issue of whether doing so adds to the discussion.
Okay, so it’s “naff”. Fair enough. Point is, simply declaring it so doesn’t say anything particularly meaningful. Now if this assertion were paired with an explanation for why it’s naff (whether insightful or bizarre), then hey — there’s a point for discussion. Someone here might have a chance of learning something, or having an interesting thought, however trivial.
On its own, though, raw opinion is pretty rude itself. It takes up space, demands attention to itself, and gives nothing in return. It is a vacuum of communication, crying “I” at the heart of the world. Beyond that, it’s uncomfortably prevalent around here. Thus the snippy response; it gets tiresome. Perhaps unwarranted in this circumstance, of course; I’m just slowly getting irritated.
