Could you perhaps be a little more respectful with your responses?

Instead of saying stupid idea don't even respond.

Or say, this isn't something I would participate in, and here's why, because I don't think this type of format would be entertaining.

You know the rule they teach you in the first grade "If you have nothing nice to say, say nothing at all."

Use it.

As for your suggestion, not even the time for place for it.
