When a fellow human warns another, to prevent them from a path leading to destruction, why is it called hate?

You see it and hear it all the time around you, on most networks, etc.. If someone turns to their fellow human, whom they see about to run headfirst into disaster or destruction, like something that may 'feel good' at the moment but be harmful to you both mentally, spiritually, & physically in the long run, maybe into other people's lives as well, and tries to warn them by telling them the problem and/or where it is wrong, the person trying to help, out of love for their fellow human, is emphatically called a 'hater' or is said to hate those they are trying to help. That is like saying that, if I see you heading out into the path of an oncoming train, that if I love you, I will not say a word to you about it, so that I won't hurt your feelings by telling you, etc. I wouldn't won't someone like that for a friend because he wouldn't even help watch your back or anything. Seems like these Christians are onto something, and everyone seems to be committing atrocity and persecution by blame
