If you are perpetuating the idea that 5G masts are spreading Covid-19, there are two possible explanations for this. 1) you're lying, or 2) you're gullibly repeating a lie you've been told and you believed. There are no other possible options. It is not a valid opinion.

The same goes, of course, for many things. Most egregiously holocaust denial, then a bit down the scale something like climate denial, then down to relatively harmless things like moon landing truthers. Bottom line, please people, stop being fucking idiots.
