That remark (which I put in brackets because it was not integral to my main argument) was meant to hint that even within LGBT community there are different positions on SSM.
A position against SSM does not imply homophobia because it is not necessarily based on hatred or aversion towards homosexuals. For instance, there is no justification in calling Eich a homophobe.
What bothers me is a tendency of LGBT activists to put a homophobe label on everyone with an opinion they do not like. That is a witch hunt.
