Generally speaking, a lot many animals are considered harmful and dangerous, even if they are not in any way so. Lizards fall under the exact same category of such misunderstood creatures. This may be because of the extreme prejudice against reptiles of all sorts, making them the "creepy" and "crawly" variety, as though it were a bad thing. What one must understand is the fact that although all reptiles are, in a way, slimy and slithery, there is no reason for anyone to fear most of them.
