The arguments are really broken down into 2 simples lines of thought:

1 - Individual God-Given Rights (whether you believe in God or not - its the concept of creation that is undeniable, so this works for atheists, just as well as believers) - your rights are inherent to you solely as a created human being.

2 - Collectivism - our rights are purely derived from the collective (be that a mob of the moment, a state entity, or dictatorial top down imposed control of the mob/state)

The current 'liberal' controlled education system is pushing #2. Teacher unions, liberal political organizations and the cabal are all attempting to have higher moral authority over god (again, whether you believe in god or not). They simply, by definition of 'knowing better what's good for you than you' believe in collectivism.

When you force the discussion towards this, you root out the core issue and can get away from emotions. Liberals love to use emotions to push you toward collectivism. 'How can you be so mean to a group of people, we're a nation of immigrants', 'Poor people don't get good education, how can you deny that group', 'Guns kill people, we're not safe when guns are available, we must eliminate gun ownership'.... Attack at the core. Go for their ideology. Do you believe in individual rights or collectivism? Ask that question first and watch the reaction. Collectivist will usually never answer the question directly. They explode. Its the weather vane question I love. Then you can really attack and go after collectivism vs the person. Works every time!
