I have found that Facebook has become mostly useless in having some dialogue with leftists (they block your posts :) ). However, I started using nextdoor.com for learning about things more local, and surprisingly, have been able to carry on some "conversation" with the leftists. The site has banned/deleted ANY political discussion in the past, but I have been pleased to find that lately that is not happening. The number of people you can reach is limited, since by design, the site is for local events, local issues, etc. However, I think if each of us is able to get through to at least ONE hopeless leftist, we could make a difference. I encourage everyone to join this site and see if you are able to get some truth out to these people.
