This has been said ad nauseum and I will probably get downvotes for this, but opposition to Trump is not about mere disagreement. The triple threat of increasing mass deportation, increasing mass incarceration, and bribing local police departments to be complicit with both, constitutes a material, physical threat to people's lives, and to certain disfavored ethnic groups (black, Latino, Muslim) in particular.
I would understand you if you were chiding people for being overwrought for saying, for example, that the Republican health care plan is going to kill people. Or that cutting back meals on wheels constitutes violence. Or whatever.
But the rhetoric on crime and immigration is literally about spending money to send armed agents of the state into people's homes to maim, kidnap, and remove them from society. If you don't understand how this rises above the level of "just politics", I feel like it can only be because you don't consider the new targets of state violence to be fully human.
And let's not forget that more than half of the country didn't want this president. Pretending this is just about the most liberal part of California complaining is incredibly specious.
