Persuasion by Robert Cialdini covers the basics of opinion wrangling. However, you aren’t going to like the bigger answer, here. In short, facts don’t matter.

The so-called left, and, if I’m being more precise, it’s anybody who craves power, regardless of the phony paradigm, don’t deal in facts unless they’re attempting to dismantle or poke holes in yours. That’s the Achilles heel of arguing with them or debating them: because you are bound by the laws of reality and evidence, you are held down. They, on the other hand, deal in feelings and promises of what might be, no matter how fanciful or idiotic.

They don’t answer questions about who pays for their massive social programs. They don’t get held accountable when they engage in hypocrisy because they “clearly mean well.” They don’t get fact checked because what they say “feels true.” They are not judged for past performance because they’re only as bad as their next promise or proposal for yet another untenable idea.

Their position is always that things are bad now because those who lack vision and heart are holding humanity back from the next step that will be the “progress” toward the fanciful utopia they always claim is just over the next horizon. Their predictions of gloom and doom always center on the creature under the bed or the menace lurking in the shadows of the closet, evidence of which can be fabricated or just outright ignored because it doesn’t have to exist.

The answer is instead to “out feel” them. Don’t worry with facts or evidence. It’s about making the audience feel good about you and your ideas. Don’t allow the lack of data to get in the way of a good narrative, because your “rightness” and “righteousness” should be all that matter. You and your ideas have to be likable. That’s all that matters.

Start reading their content. Rules for Radicals by Saul Alinski. I guess a good book by someone on the dissident right is SJWs Always Lie by Vox Day. I'd also say start reading "Go Free" by Jason Kohne if you are looking how to use better rhetoric against antiWhites who call themselves leftists.

Know your enemy, and audience.

The Art of The Argument is a good starting point for articulating a rational argument based upon reason and evidence.

Holy crap. Perfect timing! Never split the difference by a guy named Voss. No is a safe yes! I heard this guy on YouTube and he's a hostage negotiator. Confirmed my belief that you do not take no as the final answer.

I wouldn't necessarily say it's good, but the talmud is the current basis for most legal argumentation in the US.
