Let them be and if they refuse to join this market, it's their decision that will make them possibly regret in future. Just possibly because some people will never regret because they did not invest money in Bitcoin.
We should accept that we will never be able to convince everyone and that is okay. What is not okay to me is if someone refuses to use or buy bitcoin because of misinformation. If someone raises genuinely valid concerns then we can consider it and have a mature conversation.
But some are simply too close minded and they do not want to hear anyone else. They have already believed in something and would refuse to be corrected. This is what really annoys me.
Since 2009, many people missed many opportunities with Bitcoin. There is no if for coming back to the past and fix your mistake.
