The liberal government, from this way right perspective, is ignoring the Constitution, seeking to force their way of life on all with blatant disregard for the Bill of Rights. The government is acting illegally enough that resistance using force to protect constitutional rights is deemed proper. This thread had taught me how ignorant many liberals are on the Constitution, putting warm fuzzy feelings first, emotionally proclaiming what the law ought to be without researching or understanding what it is, why it is. They don't seem to understand their intellectual opponents are fighting for. The bulk of the violence with regard to the abortion question is also coming from the conservative side.
Most liberals perceive democracy and non violence as sufficient to achieve their ends.
Thus violence, always a last resort, is not yet on the table. Most liberals cannot see an issue worth fighting for, or a fight that cannot be won without use of force. It is only the far right conservatives that are getting truly desperate, that see their central values as embodied in the Constitution in danger of extinction. To avoid internal conflict, acknowledge the right to keep and bear arms. Respect the religious views of the conservatives on abortion, but insist that religious freedom means they cannot force their religious beliefs on those who disagree.
