My mother is progressively falling down the conservative pipeline and I don't know what to do, please help

I don't have anywhere else to talk about this, so here was my best bet, apologies in advance I just gotta get this off

Ever since the coming of the election I have witnessed my mom get infinitely more political, She's consuming more rightoid propaganda by the minute, she cut off any of her liberal friends because they were (rightfully, mind you) tweaking the fuck out about the election, so on, so forth, the deck is not shuffled into my favor. Recently while we're driving to college she brings up the newest bullshit in the car, and I have to sit through her ramble about shit she likely knows jackshit about, and it's starting to get on my nerves.

Recently she talked about DOGE finding the spending habits of the US government, examples being trans healthcare in Guatemala and the iraqi sesame street, something something "this is what we voted for," all bullshit, I didn't know what to say, I'm never prepared for the shit that's about to come out of her mouth, I wasn't prepared for her to deny climate change, or for her to go on some rant about the LGBTQ+ (which she's calling the LGBQ because the US shat all over trans healthcare) "being so radicalized" and the revocation of gay marriage being a punishment? I think that was her thought process, backwards as any conservative thought process, either way I'm not prepared for this, trust me I could smear the shit out of any argument or rant she makes with ease... given I have the comfort of a nondescript amount of time to respond, along with the sheer safety of my reddit account, but in person off the top of my head I can't really do that, and that's excluding the fact I am naturally not a confrontational type of person

So, what do I do? I can't just let her go deeper into the alt-right shithole, however it's not like she's going to be willingly coming out anytime soon, she isn't a smart lady after all (she's a law of attraction believer,) I could confront her, but I can't guarantee that it'll go right, if I do confront her I need to do it right, and I don't have a good enough read on her to curb that shit out, I mean, I have some solid arguments against a lot of things but I don't have them off the top of my head

(sorry this post is kinda a half vent-rant than an actual question post, uh, sorry :/)
