liberals will never understand:

1) electoral politics are optimal for incremental change. their purpose is to prevent radical deviation from the status quo. this is why, as useful as bernie & corbyn have been for de-stigmatizing the left, any truly leftist movements can't be voted into action.

2) to overturn capitalist systems, a people's revolution must come from the bottom and will be met with [violent] oppression. this is why leftist groups cannot rule out a militant aspect to their theory

3) if you are a pearl-clutching type of person who prefers peace over potentially violent justice, you're not actually morally good; you're self-gratifying moral garbage.

4) if you truly do support justice by any means, you have nothing to lose with leftist politics; capitalism is inherently violent through exploitation of land, labor, and people, and any leftist movements are attempts to resist and overthrow those oppressive systems
