Why centrists and non-radicals should support Bernie Sanders for president

Centrists, non-radicals and some self-professed conservatives should seriously consider supporting Bernie Sanders for president. There are several reasons for this.

1. Donald Trump, exactly as Sanders argues, is the most dangerous president in modern American history.
2. Climate change is so advanced and so threatening that it is no longer radical to demand major changes to our economy in an effort to reduce emissions.
3. Both the Republican and Democratic parties have shifted so far towards corporations and against the basic civic good that Sanders' platform is not as radical as it may appear.
4. Most centrists and moderates are not as opposed to organized labor as strongly as the corporate interests of the two major parties are.
5. The damage done to America's civic integrity over the last forty years is so substantial that it will take an entire movement to fight back, and Sanders is the candidate at the helm of such a movement.
6. Most of the stances on social justice that Sanders takes should be acceptable to centrists and moderates.
7. The other candidates in the race are unwilling to fight for people whose lives are appallingly difficult.
8. Basic human decency is at the core of Sanders' social program, and conservatives should be asked to show basic human decency, often rooted in their Christian beliefs.
9. Sanders' tent should be wide enough that there should be a debate AMONG his supporters over whether his platform is too extreme or too moderate or in the right place in between; if there are no centrists supporting Sanders, then only his most ardent, far-left supporters have influence over his campaign.
10. If Sanders' supporters are becoming too radical then there should be push-back from AMONG his supporters that this radicalism could grow dangerous.
11. If liberals and moderate liberals who agree with all of this can find more time to discuss the Sanders campaign with centrists, then the movement that Sanders represents will seem less threatening and more reasonable to skeptical voters.
