Here is a further explanation for the last part of that poem. First of all, we should all strive to love everyone however not everyone else will show love towards you. When you encounter a hater, don’t hate them back, simply ignore them. Its there job to hate you because you have something that they want. They will hate you until they become more secure with themselves or find someone else they hate even more. So yes, try to love everyone but avoid people who are full of negativity and want to bring you down. Those types of people will treat you horribly and then say statements like “arn’t you supposed to love everyone no matter what?”. That is part of their messed up mind games so they can have another chance to show their hate towards you again. Life is too short.
