Those who hate Bitcoin are people without mind in their heads because someone who has a little knowledge about finance and freedom would accept Bitcoin without any obligation.
Since some people are quick to adopt what other people say without trying to find out reasons of their own, the hate speech may make some people never know what bitcoins really are. But the people that hate bitcoins are helping bitcoin in a way because anytime they express their hatred for bitcoins, people will always wonder why they hate the thing called bitcoin so much. They may indirectly be helping to tell people about bitcoins and raise the interest of people to want to know what bitcoins are.
