Do a movement's supporters influence the legitimacy of that movement?
In other words, if you support the principles, ideals and arguments of a movement, but you find the movement's advocates repulsive, does that affect your willingness to support that movement? Similarly, if you support the arguments, et al. of a movement and you love its supports, does that make you fight for it harder? Even further, if you don't agree with the arguments, et al. of a movement, but you admire and respect its advocates, does that admiration and respect make you reconsider your position or support them in spite of your reservations?
Example: You are against same sex marriage morally and you support it politically, but you've interacted primarily with militant gay rights activists who castigate anyone who differs with them even a bit. Do those people reduce your willingness to support gay rights?
