You've continuously refused to define opinion for me and continuously refuse to put anything in your own words. You throw paragraphs of strawman at me because I'm being unclear. You throw 3 dictionary links in my face with at least 25 different definitions and can't zero in on a single one.
Back at the top you said:
> An example of "corporate opinion" off the top of my head: Facebook is in favour of advertising.
Can you first confirm you said that and you stand by the statement? If you do, explain to me how Facebook saying "we are in favour of advertising" is an opinion.
Now explain to me how "I like rain" is different and not an opinion. You told me "I like rain" is "a factual statement derived from your opinion" and not an opinion and then used that to strawman my argument.
Where I stand "I am in favour of advertising" is the exact same format and is not an opinion from YOUR definition. So how about you explain exactly what you want from me because your contradictions are confusing me.
