Everyone more or less laughed and made fun of special children (and also "weird" or "abnormal" people) at one point in their lives, you'd be lying if you deny that.
My question is,
Why do we laugh?
Is it because it is genuinely funny, thus we laugh?
Is it to make ourselves better? if so what's the difference?
It is genuinely funny because they aren't normal.
Is there something wrong with that?
It's because they're different and unique. That's why they laugh and make fun of them. People nowadays have this mentality where they make fun of others for them to feel better especially in the internet. It is bullying and it's not funny. I believe that those who make fun of others especially the special children will have their own taste of karma someday.
