I would suggest you don't leave but instead look at things a little differently. I don't think Jim's goal for this site from the beginning was to be a place to bs about 'ideas' like the back of a coffee shop. Although the platform is a forum, (and Jim, correct me if I'm wrong), the intent of this site was to be a platform for conservative activism. The values that the site is fighting for is set in stone, Jim mentions those many times. What is up for discussion is how to fight for those values.
In other words, this isn't a 'debate club'. You can debate on a thousand other sites. This site should be about 'what's next'. How do you act on the values that unite us.
Not everyone agrees on everything. You can choose to fight it or focus on the areas you agree with and what drew you here. It is like eating dinner with your in-laws. You can agree how wonderful their daughter is and avoid subjects you disagree on and everyone is happy. :->
Stick around. I think I speak for a lot here in that we really appreciate people who has the service history you do.
Very well and very politely put.
