just because you do not find something funny does not mean its not meant to be a joke
God, Jesus, Sex, Homosexuality, Heterosexuality, being white, being Asian, being black, being jewish (im jewish), being catholic, being a woman, being a man, being a turtle

all these things you might not find funny subjects either but I on the other hand I have heard plenty of funny jokes on all of these subjects.
humor is like any other form of art and is completely subjective one person looks at a Monet and sees beauty another looks and sees complete crap.
Just because a particular subject hits too close to home for your taste does not make it a serious statement as long as the person saying it only meant it as a joke. And even if they did mean it as a serious statement what happened to "sticks and stones will break my bones, but names will never hurt me?"
its hilarious that we tell our children (or used too when grew up) that if a bully calls you a name in school to just laugh at their ignorance and walk away but then as adults now we tell each other that if someone calls you a name you should try and make it against the law for that person to speak???? This makes no sense?
Since it is up to all of us individually to decide what we think is humor or not then I personally don't think that any of the jokes I have read within these forums were anything but attempts at humor, funny or not and I am sure that if people really wanted to bash epileptics on a personal level they could find an epileptic hating web forum for that purpose (you can find anything these days) and wouldn't go to the trouble of posting intentional hate posts on a video game website lol that just sounds silly
Its funny but people forget that in a lot of countries (including mine) the rite to say anything that was on your mind without prosecution was such an important one that they wrote it down on paper and said it was a common rite for all humans.
I am not sure and you can correct me if I am wrong about this

but i do not think any civilized country put into writing that you have the rite to stop other people from saying anything that you do not personally want to hear.
My uncle fell many years ago and is paralyzed because of it for the rest of his life and he is the first person to belly laugh out loud when a good cripple joke is told

if you asked him why he is laughing he tells you because laughing feels good and the joke was funny.
Bottom line is i don't care if you don't find something funny just like you shouldn't care if i do, that's our rite

but wanting to censor the world from things that you don't find funny so that I may never hear them and decide for myself? this is not ok with me.
hope your mom and friend have better lives in the future
