Refusing to acknowledge the rightness or wrongness of something is irresponsible.
How is this a matter of ‘right’ or ‘wrong’?
It isn’t a moral issue, after all.
There is massive evidence that some people have seen things, and some of them have decided thoughts about what they’ve seen. Others who haven’t seen anything have been convinced by the recounted experiences of others. And some people don’t know WHAT the hell to think about it all.
It isn’t even a matter of ‘true’ or ‘false’. It’s all unknown and subjective.
