The fact is, you can rail against my conservatism all you wish. You can make fun of my Tea Party gatherings, and you can ridicule patriots in tri-corner hats until you wet yourself from mirth, but one thing is for certain: my political philosophy will NEVER be a threat to your freedom. If you feel a burning responsibility to the poor, conservatism will never prevent you from working 80 hours per week and donating all of your income to charity. If you feel a strong sense of pity for a family who cannot afford health insurance, my political philosophy will never prevent you from purchasing health insurance for this family or raising money to do so, if you cannot afford it, personally. If you are moved with compassion for a family who is homeless, a conservative will never use the police power of government to prevent you from taking that family in to your own home or mobilizing your community to build one for them.
However, you cannot say the same for liberalism. If I choose not to give to the poor for whatever reason, you won’t simply try to persuade me on the merits of the idea — you will seek to use the government as an instrument of plunder to force me to give to the poor. If we are walking down the street together and we spot a homeless person, using this logic, you would not simply be content with giving him $20 from your own pocket — you would hold a gun to my head and force me to give him $20, as well.
Everything that modern liberalism accomplishes is accomplished at the barrel of a government rifle.
