Liars lie. You can tell they're lying because their lips are moving. I don't listen to liars. If I can't call them out because they block my comment, I don't pay any attention to them. If people are willing to discuss stuff, and facts can be brought up and considered in conversation, they might be wrong, but that can be revealed in discussion (which is why liars don't allow discussion), and the actual facts can be understood.
Like here. You may not respond to my comment, but you don't block comments, so whatever sources I can dredge up to refute your comments can be shared to everyone that listens to your comments and considered right along with them. That's how I know you're not lying, whether you're right or wrong.
Thanks!
