However if someone wanted to say “I am not going to read Mein Kampf because it was written by a brutal dictator who have his sights on world domination and the extermination of what he thought was a lessor race, and was a jerk to boot.” Then that is perfectly fine. Alternatively, if you want to say “I have no interest in reading it because I hear that it is propaganda and it has been offically classified as propaganda.” then that is acceptable.
It is not about subject matter but that particular source of information. If you notice the poll above, only the yes responses have a direct opinion of the movie and not the subject of the movie. The no answers asked why or why not. Same thing with Paul Ryan’s speech that was referenced in anther thread, I did not read the transcript and therefore I was not qualified to make a statement on the content of his speech.
Think of it this way, if someone says that what is going into a retail space a few blocks from City Hall is an Adult Use because they sell items of questionable content. Until you actually go in to see for yourself, and determine that based on square footage of the area in question and find out that it is actually a retail business… as in the case just down the street from you, third party information is not actually suitable to make a direct judgment regarding the content. Maybe about an opinion if you want to peruse further investigation, but not the actual content.
The other part that I find interesting is there is all these opinions and as of the time of this posting, no one in here as actually seen the movie!
