Shutting it down will certainly pander to the people on the right because their side is currently in charge and whenever their confirmation bias is challenged, they lose it.
In reality, just shutting down this section is not going to eliminate political discussion. You are still going to have political comments being made in threads and as long as they are right wing, you will (based on observation) probably allow those to slide. The comments opposed to authoritarianism will likely be deleted.
When the roles are reversed and when the left is in charge again, the right wingers and the "neutrals" will desperately want to discuss and attack how horrible things are and more than likely, they will be pandered to again.
The CE / Pol sections would probably be more manageable if none of the mods / owners participated but simply policed the forum without interjecting comments but instead conducted the policing by sending DMs to participants who actually violate established rules. This means you would actually have to establish and publish rules at least rules that adhere to your sensitivities, e.g. no strident comments, etc. Seriously, just how many referees play in the game they are actually officiating? Hint, the answer is "None".
If you really want to "shut this down" you should consider making a rule that completely forbids all derogatory political remarks, period. Anyone calling names like Newscum or

ler or lefties or

s (among dozens of other kinds of comments) is simply going to ignite the fuel, once again.
You cannot expect to run a site devoted to firearms, in California, and not create a highly charged political environment unless you establish firm, not wishy-washy rules and stick to them. You seem to think you can be all things to all people and run this like a kindergarten where everyone keeps their mouths shut for the sake of peace and harmony. You can't possibly do that without a huge investment in time and you've made it clear, you want to grow your web business, not manage the people who frequent it.
PS. You should also implement strict rules against direct and indirect personal attacks and abusive comments to and about other users. All these rules should apply to users, mods and owners alike.
