Joining late but still wanting to join this interesting thread!
Being a JW we have a lot of 'controversial' beliefs, but I think the worst one is no blood transfusions. It's one that few people actually bother to ask about, all they see is headlines screaming 'Jehovah's Witness allows son/daughter to die for God!' - which can be SO frustrating.
Most of my family is quite good about tolerating others beliefs, as we have quite a few different beliefs in the family. There are one or two who are quite outspoken about JW's only, but you soon learn who you can talk to and who's gonna give you high blood pressure!
