How about discussion about different anti-COVID vaccine from different sources - are you really treat Western vaccines and Russian ones as the same? These two give you kind of different political effects when you can visit one list of countries with one vaccine and another list of countries with another one. I do not remember any discussion like that with any other vaccines.

And by the way, there were a lot of changes of upvotes/downvotes near my comment, thank you for not being silent about such controversial topic.
