There are many things I joke about, and none of those things have occurred in this thread.
1 ste·reo·type transitive verb \ˈster-ē-ə-ˌtīp, ˈstir-\
: to believe unfairly that all people or things with a particular characteristic are the same
Stereotyping is claiming everyone who shares one characteristic as being the same kind of people.
It's making false connections and claims about the person.
It'd be like me going "All people who go on the Internet to talk with online people are lazy and can't be social. Therefore you are lazy and unable to be social".
Or say I looked at your profile pic and said "All people with two girls kissing as a pic are horny and perverted creeps. Sexual harassers and see women as good for nothing but sex". According to you there is nothing wrong with me making these claims about you or anyone else who happens to fall under the judged characteristic.
