Do what YOU want and don't be pressured into something you DON"T want to do. To demo or not to demo, it's up to you and not someone else. You owe no one anything!

We STILL live in a time where 90% of people decide what the truth is according to their feelings. Those are the ones who don't bother with the inconvenience of having personal supported explanations for their claims.
