One member of a party supporting something does not imply the party supports it.
The Greens Party do not support internet censorship, some of the members do - even with strong minor parties like we have in Australia it is impossible to align yourself entirely with the party's standpoint.
A more controversial issue would demonstrate this; Say, same-sex marriage, Federal Labor do not support same-sex marriage, but individual members do.
I am a member of the Greens (as in, attend meetings, pay membership, vote on policy) - but are not particularly in favour of much of their hard-line environmental policy, (I am, what is referred to as a Water-Mellon Green) that does not mean the party do not support these things, just myself.
