Many societies have tried to force right-handedness onto left-handed children ("forced laterality"). The general experience is that such attempts are not entirely successful, and cause distress. Writing is a case in point. A right-handed script moves towards the right, and the righthanded writer's hand reveals what has just been written, which is good feedback. When a left-handed person writes a right-handed script, their hand obscures (hides) what has just been written. That interferes with the natural visual feedback to the writer. So the way our alphabet is written, moving to the right, is better for right-handed writers.
