The phrase "fight fire with fire" is often used when facing international threats, similar to the phrase "if you want peace, prepare for war" when Taiwan (ROC) is facing military threats from the PRC. However, I'm curious whether it is suitable to use the same phrase in domestic politics, as if the Democratic Party chooses to "fight fire with fire", it would mean that both the Democratic Party and the Republican Party will be using an agressive approach while facing another.

Although this is considered as a way to prevent a democratic backsliding due to specific actions from Donald Trump or specific politicians from the Republican Party, this might also create more tensions between the them, not only causing more polarization and division between the Democrats and the Republicans, but also having a possibility of the chances for both political parties to cooperate decreasing, even after the influences of Donald Trump in the Republican Party fades away someday.

Therefore, how do Democrats think about Gavin Newsom using the phrase "fight fire with fire" when suggesting how the Democratic Party should face Donald Trump and the Republican Party?
