Being left handed myself, I have never experienced this. When I write, the paper is sideways a bit, same with drawing. And not being able to read as they write? Unless I am an unusual person, I am able to do this just fine.
People say the left handed people are not as good as right handed people. Back in the middle age times, they would force kids to write with their right hand, even in the 20th century they did this, it was considered as a disability. But we are far from being the "lesser kind" with a "disability". Left handed people are just as good as right handed people, there are no "master races".
I am a left handed person. I do use my right hand for most things as well.
