This is something that most people engaged in internet discourse could learn as well. It's often not productive to write a long response to a pithy sound-byte argument.

Not only is that losing the engagement economy, but onlookers to the thread are far more likely to read and latch onto the smaller soundbites. Longer replies also give critics more gristle to latch onto - you may think a long post covers all its bases, but you're really just giving people more avenues of rebuttable.

Better to be succinct, and if important context is left out, respond to it as concerns are raised.
