Maybe even worse than the OP
“You can and should have a sparring partner in her” but you can NOT use facts and logic in any of your “lively disagreements”, that would be debatebro which is a red flag and gives her the ick.
Reminder to never ever *debate* your girl. You can (and should!) have lively disagreements about politics/society/culture with her, you can (and should!) both speak frankly, and you can (and should!) have a sparring partner in her.
What you absolutely must not do is push the big red button in your brain that says "dEbaTe". You then enter an entirely different psycho/social/emotional register of gotchas, facts & logic, speaking fast like Ben Shapiro, "This House Believes" etc.
Importantly, this is neither gender's fault. Men are (often) socialised into a weird non-cooperational debate mode where if you ask "source?" often enough you get to be the leader of your local high-school nerd team. Women are (often) socialised into an emotional panopticon where disagreement is seen as open hostility. Your job as 21st century men and women is to overcome this.
Crucially, the emotional subtext of the conversation should always be "we are on the same team". This is important because politics is "we are on opposing teams". So you both should make an effort to tune out propaganda and be two people sharing a safe, warm little corner in this mad mad world.
