Scepticism as a method of questioning is theoretically healthy, but scepticism as a worlview is actually very unhealthy. Sceptics are only ever sceptical of things that oppose the standard scientific worldview. They are not at all concerned with finding truth, all they want to debunk anything that is 'out there'. Really they are just a bunch of hack conjurers who like to play at being scientists. Don't believe me? Here is a youtube video of a scientist saying the same thing:
