Why does everyone hate on Wiccans?

I have been a practitioner of Wicca for a number of years now and I have encountered a lot of Wicca-hate. There are some people I expect negative reactions from such as older, more traditional people and some Christians. While I do not like these reactions, I understand where these people are coming from. What I don’t understand is why younger, non-traditional people have such negative reactions. Non-religious college students who have no problem with Christians, Jews, Muslims and many other religions seem to have negative, derisive or just plain mean stuff to say about Wicca. I would like any thoughts the collective has please.
