I once met a family who doesn’t eat Gebrochts and who holds that potatoes are Kitniyos “just in case”, to use his words. I honestly don’t know what they eat.
Not to eat potatoes ‘just in case’ is wrong. Plain wrong. I know some people wont even drink water unless its been passed by a rabbi. But not to eat potatoes is crazy. The whole kitniyos thing is already a chumra. Taking on ‘stupid chumras like that’ (words of my LOR) of not eating potatoes place undue pressure on the entire family.
I’m more concerned with having what to eat until pesach.
The year that the Terri Shiavo incident was occurring, it was right around pesach. My family was walking around saying we were “starving like Terri”. (Because they pulled her feeding tube and starved her to death).
