Again, you missed the definition of propaganda completely. I don’t agree or disagree with the post and haven’t even read it, TBH. Your posts have a fairly strong bias so it’s not hard to determine what the articles are going to be like.
I should also point out that you said you are just sharing articles you find interesting and then knock Lemmy on diversity of opinion. So, it seems your point is that your article posts are a reflection of your own opinions. Totally cool.
You just need to realize that this is the dictionary definition of propaganda, especially when it’s political in nature. (Maintaining a news community without bias is exceedingly difficult, btw.)
If you can agree that your political posts are made with the intent of sharing your opinion and influencing others opinion, then you must also agree most of your political content is also propaganda. It doesn’t matter if the article was “wildly shared”. That is actually irrelevant.
I have never considered doing that at all. It happens naturally in the middle of conversations.
