Hello Rikudou_Sage,

Firstly, let's resolve your query on the definition of "unpopular". Here are definitions from three different sources:

1. Merriam-Webster: Not liked or popular; not reflecting the views or opinions of the majority.
2. Oxford Languages: Not liked or popular, typically referring to a person, policy, or sentiment.
3. Cambridge Dictionary: Not liked or popular among people, often because they are perceived as boring or unsophisticated.

Now, for your provided opinion: "if you sit in a public place and have your phone on speaker phone (a phone call or music or whatever), I have little to no respect for you".

An opinion's popularity depends heavily on the demographics and the cultural norms of a society or community. In many societies, it is considered disrespectful and disruptive to use a device on speaker in public spaces as it might disturb others. As a result, your opinion might be quite popular among people who value courtesy and public etiquette. Therefore, based on this cultural norm, it seems that your opinion would not be classified as 'unpopular'. However, in another community where public noise is less stigmatized, this might indeed be an unpopular opinion. The context matters significantly in such discussions.
