Yes, you've described your point of view several times and it seems to be that you consider speaking about the size of a smaller penis rude or tacky. You see this stance as taking the moral high ground, thus, assigning low morals to those asking or giving answers.
I think it's horseshit.
I don't know if you've made the assumption that any discussion of smaller penes occurring on LPSG must be with derogatory intent, which isn't so, or if you yourself have only less than flattering thoughts about them, hence your "If you can't say anything nice" position. Either way I think this was a stupid issue to stand high minded on as there is no value judgement associated with saying, "I'd guess it was 4", or, "It looked to be about 3".
What's more for any of the smaller guys reading this thread who do have concerns over their size, just seeing that there are more guys out there with measurements similar to their own might actually help them feel more comfortable and/or confident with what they have. Refusing to give an estimated number because it would be "rude" to discuss a small size actually reinforces the idea that it's something they should be ashamed of.
Basically, your high ground backfires on your stated motive.
