Is it normal that I hate people who self harm?

As a cutter, I think it's sad how ignorant you are on the subject.

People cut for numerous reasons, so much so that even as a cutter myself, I do not understand all of the reasons.

Sometimes people feel out of control, as if there's too much noise that you can't escape from, complete silence can sometimes make it ten times worse, and they cut to regain control and power over themselves to make everything calm.

I myself cut because despite the noise I use to try drown it out, everything is just always silent, but a sharp silence, and I have a facination with blood (Not in a vampire-wanna be way, I like the deep red colour), it stops that sharp silence for a while.

I remember seeing a video from someone I watch on Youtube saying his reason on why he cut, and his reason was that someone had hurt him, or numerous people did (can't recall it perfectly), and when he cut, it was to show that nobody could hurt him as much as he could hurt himself. He done it to control his feelings and to not feel vulnerable.

The reasons for cutting are different from one another, so much so that you shouldn't treat it lightly. I remember thinking in a similar way to you about it, but having experienced it and the need to, I facepalm at my past ignorance.

You don't have to like it, don't get me wrong, but don't be so cruel as to think they are less people because of it.
