Crazy people such as yourself always say things are self evident. You are only speaking about what you think which is already highly suspect in your best moments. This outlandish claim needs to be backed up or no one is convinced.
Many things ARE self-evident. Would you say that fish being good swimmers is not self-evident ? You think you need a study, and
"data", and
"evidence" ?
How about man on bike is faster than man on foot ? Need
"statistics" ? How about broken glass is sharp and can cut human skin ? Need evidence ? How about water moves from higher elevations to lower ones ? Need data ? Need to be
"backed up" ? How about oceans contain salt ? Want t cal that an
"assertion" ?
I'll tell you what else is self-evident. That by trying to employ your age-old liberal tactic of demanding data, statistics, evidence, for that which, obviously, no evidence is needed, you have made a grade-A fool out of yourself in this thread. Sometimes statistics are needed and useful. But in those cases where they are not needed, to come in here demanding them, only makes you look like a fool.
