Why Can't Fundamentalists Simply Have Fun?

A few days ago, I attended a party, which I was invited to by a woman my sister and I know, named Valerie. Both she and my sister are Holiness christians. However, what Valerie neglected to tell me, in her invintation, was that she had invited a pastor from another church to come and speak. Now besides being put off by her deception by omission, I was also offended since I happen to be a deist. I think that she even knew this when she sent me the invite, through Facebook, and that this might have been why she arraigned it in the first place. Luckily for me, I was able to sneak away unnoticed, while they were assembled. Yet that was still time which I was cheated out of. I had expected to be attending a friendly gathering, not Vacation Bible School. Also before we were to start the three legged race, some wise guy asked if Valerie was trying to encourage homosexuality, with us being tied so close together. What homophobia many of these Holiness people have! Please, can't christians just have a good time without it turning into an evangelistic outreach? I've noticed that about anything you can imagine doing they attempt to christianise. Like for example, Valerie and her family are members of "Cowboys for Christ", there is also "Fellowship of Christian Athletes", and even christan clowning. Now just what exactly does any of these interests have to do with Christianity? Like I should know who amongst you are christian, just as you all know that I'm a deist. If I want to know anything about your religious beliefs, I will ask. In fact I once had friends who were Catholic. And I questioned them about what they believe until they probaly grew tired of it. And if I were to visit any friends who are muslim, would I have to expect to be exposed to there "salat"(prayer), and/or "dawah"(witnessing)? Or what about wiccan friends? Would I possibly encounter them casting spells? I feel that people should respect other people's sensitivities, and not subject them to religious activities. Especially against there will, and knowledge.
