As others have pointed out the OP's dislike of newer memes is merely a function of age and/or conservatism. But there is a deeper criticism to be made of memes. They are often a thought killer. As with much humour on the internet they are often used as a form of social control within a group. Thinking maybe some Other has a reasonable point? Boom: a hilarious meme that shows why people who consider the Other's ideas are just vacillating ninnies. You laugh at your reasonable self. Thought stopped. Memes are really good at that.
