Can I hate baby boomers?
That depends. What has made you hate baby boomers?
Because they are selfish, greedy and have taken the natural environment for granted.
it is wrong to hate people based on their age group. You will miss out on meeting nice people if you do this.
Maybe that's true. But I can't help it but feel how I feel about them.
But there is something you can do to change how you think. Not everybody who is in that age group thinks the same way. You should talk to more people in that age group so that you can get to know them and see that you shouldn't hate all people from that age group.
