Are people telling the truth if there are a lot of them?
The odds are that some of them at least are.
And my personal impressions after speaking to them over the decades on the issue is that most if not all of them are being truthful, to their belief system.
Don’t mean to be argumentative with you on this one, but I can’t buy into your assertion of that they’re all lying, that 0% of them are being truthful. It’s not what I’ve seen.
