"When I conducted a survey of 235 Doshisha University students a few years ago asking their opinions about the Gakkai and how much they knew about its peace education programs, over 80 percent responded that they had a negative image of the movement and about 60 percent thought that its 'peace movement' is little more than promotional propaganda. The few respondents with a positive image were either Soka Gakkai members, were related members, or were friends of members."
