Legitimacy
Because his activism has provoked opposition, some have speculated that Phelps might be an elaborate prankster or agent provocateur. Such speculation has come from conservatives who believe he is consciously trying to discredit social conservatives, and "some among the extreme-right have speculated that Phelps is a plant aimed at giving the anti-gay movement a bad name". Author Keith R. Wood suggested in a 2004 column that Phelps' protests "are most likley (sic) being funded by NAMBLA" and are designed "to draw unfavorable attention toward Christians as a whole, make [them] afraid to speak about morality, and make [them] all seem like idiots."
Phelps' estranged son Mark has said Phelps "simply wants to hate and to have a forum for his hate. . . . If it weren't the homosexuals, it would be something else."
