The vaccine is NOT the issue that is separating your parents. There are deeper and longer-term issues that this hoax pandemic has exposed. Your father seems irredeemably cucked and will correctly face all medical and psychological consequences that stem from his taking the vaxx. But even if he were to take it, he would be no better off - not because he could die from it or be injured by it - but rather because his wife would lose all remaining respect for him. A man who is easily and emotionally controlled by his wife is a man for whom a woman has minimal respect for, and so it is easy come, easy go regarding these types of hombres. As a 60-something, immuno-compromised female, your mother doesn't seem to have too many options and she should know that her market value isn't too high, and that she really won't have any better offers. It's also puzzling why your father is moving out if your mother is the one who is upset and thinks that she can do better, isn't it? This fake pandemic hoax, and the vaccine poison that has emerged from it, has brought out a lot of underlying, long-term issues that clearly existed in your family and in your parents' relationship. So, in sum, the actual issues aren't about the vaccine here, but about people having unresolved issues that they are conveniently transferring towards the vaccine. Your father, who may be a nice guy, needs to man-up and stop being such a push-over, cause the power dynamics favor him clearly. Also, what's up with all these milquetoast Q and Trump followers who abandon ship and become enthralled with the poison vaccine? I see the same conspicuous behaviors from some libertarians as well. Oh, well, it seems that fear and virtue-signaling are the primary forces driving the sheep to the slaughter via their desire to be injected with the poison vaccine.
