Ban guns, so nobody can easily use it. What happens next? Other tools become instrumental. Take the UK, for example. They are trying to ban pointy knives now. Do you see a problem with the approach?
But did banning guns there reduce crime and violence? If yes, how much? Was the tradeoff between less crime and fewer gun rights worth it? These are interesting questions, for which I don't know the answers. But just saying "they'll ban knives next" is not an argument in and of itself.
Some known gang member decided to use it, so let's punish the law abiding people.
And this is why I hate the fact that gun control / gun law has become a political football. Because the real answer is: Many known gang members and other criminals decided to use it. So let's try to (a) prevent that, and (b) screw with some people who are reliably republican voters.
Not yet, but do you have a slightest doubt it's coming up next?
(About a ban of possession or PPT of Glocks): Yes, I very much doubt it. California has only very rarely prohibited all transfers of a class of guns (that being assault weapons and 50BMG), and only once to my knowledge prohibited possession (meaning confiscated) guns, namely some SKS during the time Lundgren was California Attorney General. By the way, he was a republican.
Who is behing the anti-gun lobby? Again, the Dem party.
Nonsense. The DNC does not fund much of the anti-gun groups, if any. They are perfectly capable of funding themselves. By the way, the same is true on the other side: The republican party does not fund pro-gun groups. On the contrary: the NRA was historically one of the largest donors to republican campaigns, and one of the largest (or perhaps the single largest) grassroots group for delivering votes.
You can check that yourself; the form 990 (annual tax returns) for pro- and anti-gun groups are all online.
If anything, it's the opposite: Politicians on both sides and their parties are bought by lobbying groups, be it Giffords or NRA.
However, I yet to see one pro-2A Dem politician.
They do exist, but they are indeed becoming rare. Until about 10 years ago, there was a significant number of democrats that got an A rating from the NRA. At the same time, McCain (the republican presidential candidate!) got an F rating after introducing some bill the NRA particularly hated. But the NRA really has morphed from being a pro-gun organization to a republican campaign group (that's why they are jokingly called "National Republican Auxiliary"), so I'd expect that. In the midwest and the east coast, pro-gun democrats are not all that rare.
And if you look around, there are significant lobbying groups (such as the Liberal Gun Club and the

Rifle Association) that organize democratic-leaning gun people.
Maybe in another 20 years. You well know the court dynamics in CA.
No case in California has gone on for 20 years. The longest I know of must be Nordyke or Duncan, which took maybe 6 or 8 years. And some gun rights cases are actually decided in months.
I am not making anyone an enemy.
Yes, you are clearly stating that your enemy are democrats (or democratic politicians or the Democratic Party). That's why we can't have nice things: As long as gun rights are seen by society at large as being an issue ONLY for republican voters, it's considered cool and useful to restrict gun rights when democrats are in power.
Gun violence problem is artificially made-up and blown out of proportion by the Democratic party.
That is also nonsense. The statistics about gun violence in different parts of the world and of the US maybe a bit inaccurate here and there, but the are mostly correct. And they are not artificially made up, in particular not by the Democratic Party. Did we just say something about "making enemies"?
