Yes, definitely do!! For example, lets say a stranger bumped into us on the street, then doesn't say sorry, instead acts like an asshole. That simple few second and literally harmless encounter, is already enough for us to feel completely turned off, and dislike that person. Or lets say while you're driving, someone cuts you off, and even honks at you rudely or sticks the middle finger at you. Once again, will already be offended and may get angry or frustrated with that person.
Now think about ALL the troubles we have to endure simply due to our parent's selfish decision. How is it possible for me not to hate them?? I understand the part where most parents didn't do this intentionally, they just didn't know better. But same as the example I just made above. Literally NONE of those people acted like that intentionally as well, they also just don't know better. But for some reason, we are more understanding to our parents (of course I understand why, its human nature) even though they forced us to endure WAYYYYYYY MORE bullshit than any stranger on the street (example) can ever put us through. Lets say if even one day we're on the street, and we get killed by some stranger. If you really think about it, if our parents didn't bring us to this world in the first place, we wouldn't even have to go through that. When they give birth to a human, they're exposing them to the potential of literally unlimited amounts of suffering.
But of course I'm directing this to mainly the shitty parents only, not the good ones. Also, whoever is on this forum that is also a parent, I'm not directing this to you in any negative way as well, but yeah. I definitely hate my parents for bringing me to this world, and now just left to rot, surivive, and die on my own. As much as I want to understand that "they don't know better"..... but what about me??? Where is the understanding part for me??? I'm just forced to play the nice guy while I'm being fucked 24/7......... its not fair AT ALL
