He explains it a bit better in this post:
I suspect we interpret it somewhat differently. I see it as saying, "If you're a conservative, here's a place you can express your beliefs, share ideas, argue with other conservatives, and advance conservative causes".
I do not see it as saying, "If you're not a conservative, we'll try to convince you that you should be one". That's a very different angle, and it would attract disruptors as much as potential converts. JimRob was very clear that people coming in from the left wing with their BS and nonsense will not be tolerated. Even libertarians catch grief from some of the hard-liners.
So if your goal is to advance conservatism, I suggest that other conservative sites that are designed and intended for that purpose, might be better suited to achieving your goal, than FR. As far as I can tell from JimRob's statements over the years, FR is for those of us who are already convinced that conservative thought, philosophy, politics, and action, are what we want. We do love to argue amongst ourselves. But we don't need to be converted.
Could FR attract more younger conservatives? Sure, make the FR Facebook site a more attractive and active jumping-in place, rather than just a bunch of complaints when the main site is slow. Maybe run an active X FR account (I don't do those social media but most younger folks live on it). With the idea being to drive people to the main site, not to replace it.
So I respect your greater years here, and join you in continuing support of FR (I do my monthly via PayPal which is hassle-free), and hope that FR maintains its spot on the internet for as long as possible. Let's continue to have fun with it as well. Have a great rest of the evening, and God Bless. :-)
