I agree that both statements can potentially be problematic in similar ways, and I was hesitant/careful not to paint everyone with the same broad brush with that comment. But there's a difference in scale and intention here.
Regarding your comment, I don't see how you can take a suggestion that someone is fueled by a "this is smart, and I'm smart for liking it" attitude without implying dishonesty. How can someone arrive at a genuine and honest impression if that disingenuous motivation is assumed? Dishonesty is built into that framing. Furthermore, the implication doesn't seem to be based on anything other than your own preference-- I don't see an actual argument there. Most importantly, though-- there's a difference between acknowledging a possibile use case that should be considered, and suggesting that it's evident/apparent/likely. The latter is the leap that makes it deplorable.
Regarding my comment, after describing the logical rules that I think we're bound to, I'm suggesting that given the rules I can comprehend about where the word "good" must ultimately come from, there are only are a few conceivable places where disagreement could come from. It could be the case that there is a fundamental disagreement on the definition of "good", which is the most likely case that I was tackling and that I explained why it didn't make sense to me. Or it could be that the word preference is being used in place of compulsion, where it doesn't belong. Nowhere did I imply that the latter is actually the case, especially not across the board in a blanket statement. It was an example of a possible defense that I could think of and why I thought it didn't work.
That's my defense for what I was trying to do. But I fully grant that if it's taken the way that you wish for it to be taken, I wouldn't stand by that and would gladly retreat from that position, because I don't believe in it. If the word "suspicions" rather than "wonder about possibility" is mucking it up, I'll gladly take back usage of that word and admit error.
It's a compulsion that I do understand, but I do think that it's a rotten way to converse, and if I catch myself actually doing that and actually making blanket statements purely out of a bad/underwhelmed impressions, I would instantly think I was doing something awful and worthy of criticism.
How would you defend your statement, though, other than by looking for something to throw it back the other way with? And do you stand by it?
