The conversation has to broach:

• Medical standards groups have our interests at heart even if medical companies do not
• trans people exist and have a right to live how they like.
• Children have a right to some self-determination, including figuring out their sexual preference and gender identity.
• All people deserve affordable health care and affordable housing, regardless of their race, religion, or background.
• Criminals deserve to be treated as human beings. Jails directly stand in opposition to that.
• there's likely more that I can't think of.

These 'dialogues' are not about things the left can morally budge on, and they're insanely exhausting, especially when your opponent isn't arguing in good faith. No one is obligated to go through that social stress, and frankly it's probably easier for most to just physically fight right-wing zealots.
