There are more ways of showing support for a dangerous mind control group than being an appointed man or contributing funds. Just by placing your bum on the KH seat everytime you attend one of their indoctrination sessions you are counted in their stats. Stats that keep the WT lie going. If you're still engaging in FS you are counted as "active" contributing to their number tally that keeps the lie going.
Of course, it's your life, but personally once I saw the ugly, ugly side to the org I just could not in all good conscience lend support to this group. I felt passive attendance is still support and silence can be interpreted as approval.
