My sister dated someone for a while who was one and she herself became very different. When they stopped dating she became her normal self again. She said it was just too weird what they believed and how they were so she stopped seeing him and going to meetings with him. I just dont like when they harass me at my door. They stood outside my door for 20mins and when I left for work they started again. This is not the first time this has happened. IMO and my opinion only I see them as a cult. I know everyone has their views but I dont like being forced to join something I dont myself believe in.

Strange your sister was dating a JW. They're not supposed to date outside their faith. If you don't want them at your door have you thought of just saying you're not interested anymore. I guess you're trying to be polite.
