Hey, pure coincidence , Johnny Harris from youtube recently put out an informative video on Joe a month ago:
https://youtu.be/sLaXSvpfDZs?si=CPwiMtAEdhaWA3Jj

His video is nuanced and informative, but I cannot say it is unbiased and it leaves with a very centrist conclusion, but this might be the best for someone unfamiliar with Joe.

If I may add my own take on him, his show should be considered purely entertainment, and any semblance to actual discourse or debate is purely coincidental and done for entertainment. At best, it should encourage people to start forming their own ideas and opinions (without actually providing reliable resources where to start proper, sadly), and at worst it validates the unfounded opinions and hypotheses of those who believe their internet look-up and echo chamber chatter is equally reputable as peer-reviewed, documented, proper research.

And lastly to alleviate any concerns you have, people who watch Joe simply yearn to be more knowledgeable, even if his show isnt a good chanel for it. Your partner may be able to understand your concerns with a good discussion and communication, so I wish you the best in talking to them and a prosperous outcome. Cheers!
