Thank you very, very much @catpaws. It is very interesting to hear that it is an issue in Russia. So far I have only been aware of this issue in the US and England.
I would say it is not necessarely that you cannot argue with people who oppose vaccinations, but rather just certain individuals. In my opinion, a lot of problems we have today, all around the world, are because some people do not want to listen to or consider other opinions. I am just trying to encourage people to argue constructively and evidence-based.
I would write a longer response because I am really thankful. However, I am pretty tired of typing so please dont take this short reply as a sign of me disliking what you wrote! I hope you have a good night!
Cheers!
