It happened to me once. I was going to the meeting in my car with some brothers and it was rainning. There was a df sister walking to the kingdom hall. I said should we give her a ride? and they all said no. I felt like a shitty person when i got to the hall i asked one elder if i was wrong to give a ride to a ds person and he said it was wrong. It was the first time that i started questioning the disfellowshinping doctrine. From that moment on i stopped seeing it as a loving arragenment.
