Criticism is easy. Take basic rhetorics, add some cynicism, attack the straw man a few times — you have now posed some compelling criticism! Compelling to morons, anyway.
Most criticism is useless. Empty thesis, empty antitheses. Entire conversation is void.
What’s the point of criticism without providing alternatives, anyway?
If the critic doesn’t provide solutions then he must hope someone else will!
This ultimately reveals how most critics have no skin in the game, take no responsibility, and no action in general. Talker are not doers.
