A certain amount of the extra added restrictions that often one finds people doing for Passover seem to me to be not all that necessary. After all what is matza? Just flour and water. Heat it up and eat it within 18 minutes and it can not be leavened, bread. The only way something an be leavened bread is by sitting. In any case, the restrictions I think are a power grab by religious authorities to make people think that we need their great wisdom.

Personally, I think the whole religious world has an aspect of being a cult. I would not go anywhere near them --with two exceptions. One would be  straight Litvak yeshiva. There the Torah is learned for its own sake. Another exception would be a Na Nach group of Breslov. Though these are very different kinds of groups, still they both seem fine to me. 

The best way to keep Passover is to do the seder at home.to make ones' own maza by making a thick batter of dough and to either put it into an oven or in a frying pan [or empty can of fish. if one does not have a frying pan.] with just enough oil so as to not stick. [a thin batter would be mezonot--cake and not considered as bread. even though one can eat it, it still is not maza.]

See the LeM of Rav Nahman volume II, chapter 44   not to add extra restrictions to the commandments of the Torah. Just to keep it plain and simple.

[I got the idea of not adding extra restrictions from the LeM of Rav Nahman. Since then I have tried to stick to what the Torah says: "Do not add nor subtract from the mizvot that I have commanded." However the religious thrive on adding restrictions. So I recommend staying away from them.]
