My dad is an ex-Catholic turned New Ager, but he's not really the lovey-dovey type so I don't think he's that similar to your mom.
My uncle's girlfriend, on the other hand... DAMN. The thing is, I have anxiety issues and I quickly get overwhelmed in loud or crowded places. So when I was at a family reunion party (I'm the black sheep of the family, the only quiet person there), I stuck it out for a few minutes before going to a quieter area of the house to recuperate. Without asking, the girlfriend follows me and sits in the chair next to mine, despite all my body language displays being set to "Fuck off, can't you see I'm minding my own business here" mode.
She asked why I left so suddenly and I just told her that I needed a break, an alone break, because I'm from a different time zone and that I get excessively anxious around people. She proceeded to tell me, without being asked, that my anxiety could be cured by just tapping myself on the back a certain way, and changing my body language. She insinuated, not too subtly either, that I was responsible for my own distress. She told me to "lean into life", and I had no idea what the fuck she was saying so I told her to explain that in conventional speech.
Then she went on about some bullshit about animal body language and that my body language was "predatory" or some shit like that. I think she was citing the look on my face as evidence, but she failed to relate this to my frustration at having an unqualified person telling me that my involuntary problems are a result of my attitude.
Eventually she went away. Later I learned from my grandmother that just after that incident, she went to my grandmother and started telling her that I was not just rude to her, but to my grandfather. My grandmother knew this was bullshit, said so, and one of her friends jumped into defend me.
But... yeah. Christian fundies are blatantly aggressive, but New Age fundies have a tendency towards narcissism (i.e, "I'm way more enlightened than you!") and passive-aggressive behavior. I remember reading once that conspiracy theories are more likely to appeal to those who have low self-esteem and few friends, because the idea that they have become "enlightened" and "learned the truth" bolsters their self-confidence. The New Age movement and conspiracy theories are so closely linked that I wouldn't be surprised if there was a clear link.
I know it doesn't compare to the horrible shit you went though from your mom. People are so willing to believe that they are in control of their lives that they'll embrace any bullshit they want without thinking of its implications.
