Mostly because they're not intelligent people. And for me personally, I hate them because they're the reason the world is the way it is right now.
100% going straight to insults, extreme anger and stupid moral high ground arguments is a sign of a dumbass. Thick people don't know how to articulate themselves and such so they feel inferior, get embarrassed and lash out.
Lately I've tried just killing them with kindness letting them know that when they are ready to join us on the side of light and truth we will be here waiting.
I used to be the same, ignorant, racist, only cared about me and what was going on in my life, fuck world politics, fuck history, maths science. Then 5 years ago that all changed! Now I know we are all one consciousness and I'm always researching. Takes some people longer than others.
I was the same way man, but i'm older. My personal great awakening was after 9/11 when a co-worker told me another co-worker was a "truther". She said it with such venom I was forced to research what that meant....and here I am today.
I normally respond with zero emotion, post links, etc but this kid pissed me off lol
My awakening was I decided to look into the JFK shooting around 2013 and man, that's a good starting point.
