Learning about wiwille

After 41 years, I finally made contact with my birth parents. After I finally received my pre-adoption birth certificate, my wife did some internet legwork and found their contact information. She reached out to both, who confirmed they are my birth parents. I found them to both be alive and well living in Washington. I've spoken to them both at length and they've provided me with a lot of information. The things I've learned:

1. I'm mostly Irish, which would explain my fascination for stout beer.
2. I have two half sisters, both of whom are, as my friends have put it, hot. I really got screwed in the looks department.
3. My birth father's wife had no idea of my existence, until I reached out to him. He then told her about me, and she thankfully was excited.
4. On my birth father's side, only him and his wife know I exist.
5. On my birth mother's side, only her and her husband know I exist.

I've been keeping this from my family to not hurt anyone's feelings. They've been good parents and I don't want them to ever think I would refer to anyone else as mom or dad, but I feel a tremendous amount of guilt because of it for reasons to numerous to detail.

Descent into batshittery

I have a friend who is now on the conspiracy theory bandwagon. He is posting on FB more frequently with videos of the same old topics of some secret society controlling all world events. Sometimes he crafts his own words, such as the below:

Dont believe the polls... Hillary is part of the illuminati...! Pay attention to whats happening in our country. Oregon has uranium.... Who own all the mines? How bout the media? Who own that? There are 3 countries without rothschild banks. Wanna know who the next 3 wars are with. ? Make sure trump wins he finances himself the illuminti wont be able buy him out.
Those who oppose trump wanting to make america great again......... Enjoy the fema camps!!!!

I feel for my friend as he had it rough growing up, and it appears life hasn't been kind since we've virtually reconnected. Now from afar, I see his descent into madness. He needs help, and I have no confidence that there's anything I can do to help.

My mother recently told me her best friend believes the Earth is flat. Seriously.

Has the whole world gone nuts? Are people still denying mental health care is a real issue we need to address?

Why?

I find it surreal that Donald Trump may possibly be the GOP nominee for POTUS. I underestimated the appeal to the narcissistic asshole demographic.
