This might be true, but some communities are more attractive than others. There is a big difference for example between communities created around things that require an effort to reach for and those that people use because it is their job, a way to get a job or (worse) are required from them in school.
Discarding a tool just because you don't like some of its users is childish, but there is nothing wrong with looking for community that you enjoy.
