FIL/MIL blame Biden for not doing something we didn’t ask them to do

So I just received our Christmas card from my in laws yesterday. In the card is a printed out letter in which my in laws go into great detail about how they were sorry they couldn’t co-sign a mortgage for us, we never asked them or wanted them to do this, because they purchased a house they couldn’t afford and somehow this is Bidens fault. I’m utterly baffled how this is appropriate for a Christmas card (albeit very late) or how they think Biden or the dems are responsible for them buying a home they couldn’t afford. They also included a breakdown of their Ssi and how they didn’t get enough of a COL raise. I truly wonder what they think is going to happen to their SSI in the next few years. There was also an entire paragraph about how if I died (with several examples of how I could die) they wouldn’t be able to cover the cost of our home. So I’m pretty sure they are going to try to unalive me at some point. But again we never asked for them to co-sign for a mortgage! I would never want them to be involved in any of our finances or belongings! My husband wavers on whether or not he wants to go low contact with them and I truly don’t understand how he can still justify this level of self centered and insane behavior.
