AB144 is definitely, without a doubt, extremely bad! There is no sugar coating this, there is no justification for this, there is no rationalization for this. Open carry IS the 2nd Amendment, always ways and always will be. AB144 simply puts the final nail in the Mulford Act's coffin on the true, unfettered right to bear arms in CA. AB144 is a clear example of the insidious incrementalism that pervades our society today (as is AB809).
Whether or not UOC has helped the 2A community is a different question entirely. From my perspective it has absolutely helped. UOC'ers reached out to many in the community who were unaware of their 2A rights and positively impacted them. UOC'ers did not break any laws nor did they harm anyone, or infringe upon any others' liberties. UOC'ers are not to blame for Lori Saldana's anti-American reaction to American's living as freely as possible. UOC'ers are not to blame for Porkantino's decision to carry socialist Saldana's cud after she failed to achieve her tyranny. The full blame and responsibility lies with those who seek only to control you, rip your liberty from you, and endanger the entire public with their failed utopian ideas. UOC'ers took their guns out from hiding and brought them to the forefront of discussion...and that was and is very positive for the 2nd Amendment.
ETA: Gov. Brown is not our friend, he is every bit the tyrant as Saldana, Porkantino and company.
