With Covid and other things going on around the world - it has been popping up on Social Media that only those who are experts in their respective field should be giving information on their respective field. If you are not a verified expert and give an opinion (even if you have done extensive research on it) then per these people your educated opinion should be discounted. Is this a proper way to live life? Do you have to be an expert in order to give informed opinions? Can a layman talk about things?
