Armchair idealist

[Sonia]

There are three types of people in the world: people who care, people who couldnt care less, and [armchair] idealists. [Armchair] idealists are by far the most annoying. These people love to comment and [criticise] others appalling behaviour yet refrain from actually moving from their seats and doing something about it. This can commonly apply to issues such as the environment, world peace, starving children, etc.
