I hate people that grew up in middle class homes with both parents
Why would hate them for reasons like that?
I observed many people with their parents who are still together, they are against abortion laws.
You really shouldn't dislike people due to their circumstances. It can be hard to see someone who had it better than you, but that's just like a comparison of circumstances. You will always be unhappy if you keep comparing yourself to others.
It's okay to dislike them for being ignorant.
If they are acting ignorant, and truly don't understand the world around them, then it is okay for you to dislike their behavior.  However, these are complex individuals just like you, and even though they were given an easier path in life, they are not to be hated.  They have every right to live as anyone else.
