I often hear from seasoned dancers “I am not going to dance with beginners or generally people who are not at my level because… I want to have fun in the milonga… because rejection will make beginners stronger… they will build character… learn to work to reach me…”… the list can go on forever. So if in a tango community, the experienced members are supposed to educate somehow the newer ones, these statements seem to me equal to the following behavior. Instead of providing a wide variety of stimuli… like tastes, smells, images, people, languages, etc. to your baby, you just allow them to eat only fruits, smell only the range of smells inside a house… see only faces of your larger family group… listen to only the same language you speak.
