I know the rantings well. My AH doesn't rant anymore because he knows I won't listen to it anymore. His were always done when he was stone cold sober. And, once he got on meds for anxiety, his rants had less of an edge to them.
According to him: our neighbors were murderers and were going to come and kill us any day(big conspiracy theory issues here), the government was going to steal our money from our bank so we need to bury it all in the backyard, everyone (and I mean everyone) was out to get him and he was going to tell me why, society is going to heck in a handbasket because of women's lib movements(ummm, yep I was a woman standing right in front of him and no, I wasn't offended, thank you very much, UGH).
I could go on but I just wanted to let you know that there are others who understand!
