Not showing up to the debate is to cede control the of conversation. It's clearly not working for the scientists. Scientists need to be represented and make their case because the strategy of avoiding taking on people like Ham has backfired.
It would be one thing if ignoring wacko creationists stopped them from getting attention, but that's clearly not the case. Scientists need to speak up if they want their point-of-view to be represented in the conversation.
Out of curiosity, does anyone who saw the debate think it is worth watching? I'm interested, but it's also nearly two and a half hours. That's a big chunk of one's day.
