Why is this downvoted? Didn’t history prove this enough by now?

No - just like I don’t want to ban people having a conversation in a pub about a topic I don’t like even if they just tell lies to each other.

If it was up to the EU we’d still believe there was no chance in the world the Corona Covid virus could have ever come from a Chinese lab and even suggesting it should have you banned from social media. Free float of ideas and let the best argument win.
