Assuming your SO is a decent person otherwise, focus on life and your kids. Don't force this stuff down the throats of deep [B]LUES, especially those you care about. Let the red pills come to them organically. They will only be convinced when MSM t[e]lls them. Facts be damned.
I have a dear friend, huge 45 [H]ater. Friendship has come to a head a number of times over this stuff. I eventually just stopped t[a]lking about it with them. The friendshi[p] went back to normal. More & more recently, they are coming to me saying things like, "I heard on NPR that this Russia thing is a joke, and they are just trying to divide us rather than pick a side…and the guest saying it was a writer from the New Yorker!"
Focus your energy educating those with even a sliver of an open mind (i.e. social media, moderate friends, etc.). They are the only ones who will hear you…for now.
Another tactic I've seen effective around hardline dems/libs (friends/SO) is to let them overhear you talking with others in a group setting. In public, [p]eople are more kind and receptive to debate. Perfect example is how divisive and mean people are on social media. Less than 1% would act that way face to face.
And, if it needs to be said, dial it back (a lot) in public. Ease people into this stuff. Stick to FACTS. Things like "no collusion"… oh Manafort? who did he really work for, things like that. Point out real examples of fake news. Despite what you/we may believe or theorize here, if you barge into a group of people talking about how Q said Hillary is a blood sucking pedo, [y]ou're going to have a bad time.
Bottom line, keep this stuff mostly to yourself when it comes to close personal relationships that involve a political divide. Live a happy life. Those with isolation/depression/broken homes/lost jobs do not make good warriors in this fight. Find your light, and adjust your tactics.
Also, stop doxxing yourselves with these "are you feeling like this?" #metoo stories. Many if not all of them are b8.
