These people are delusional...
Yes they are. If their delusions were from some genetic defect or chemical imbalance, I'd have sympathy for them and want them to get help. I've known too many of them, hell, probably was very much like them at one time. Their delusions are their own choice; they can wise up any time they want.
In the meantime, in between time, ain't we got DUmmie FUn?
