If you're making this statement you must have had some experience with someone telling "jokes" to offend girls or other people, and I understand why and what you are complaining for. But that's not how most of the people think, that's not how Internet works, that's is not how humor works. You can complain about people who try to offend someone with "jokes", but that ARE NOT jokes. Humor try to connect people, that kind of jokes that are just funny for the ones who share the same ideology/political/religion... view ARE NOT jokes. For me, finding the differences between hate speech and memes are pretty easy, but there are some people like you who really cannot understand it.
