If we can't discuss politics ...
And our style of "discussing" politics is throwing insults at each other ...
Then we can't discuss gun control law, in particular not California laws, and how to make our situation better in this state.
Because any mention of a gun control law will cause people to go off claiming a variety of political things, for example that it's all libtards faults, no it's all Reagan's fault, no Trump will fix it all with his sharpie, no Trump is the problem not the solution, and so on.
We could try to educate forum members to try to discuss gun control laws and politics in a civil manner, without insults, without over-generalizations, without throwing accusations. And punish anything that lacks decorum with temporary or permanent bans, or having posts deleted or redacted. I actually think that it would take remarkably little effort by admins and moderators, because (a) a lot of posters would get banned very quickly, and (b) the remainder would learn to be polite.
Note that the above remarks are only about gun law, legislation, regulation, and politics. Generalizing that to discussion of other politics (immigration, taxation, abortion, ...) is very unlikely to work with the people present here, and should not be attempted, except in a very isolated and sterile cleanroom.
