I don't believe gay male porn is equivalent to straight porn. Where have you got the statistic from that most porn is gay porn? I have not heard the proportion of gay to straight porn being lower than 1:30. There is far more discussion, debate and exposure of problematic production companies within the gay community, despite them actually having a genuine reason to believe that such debate could be used to limit their sexual identity outside of porn use, which straight men don't have to worry about.
The issue of Eastern European twink porn being hugely exploitative has been widely debated within the gay community, with people looking at ways of addressing that, despite the content of the porn itself being vanilla and not particularly controversial.
It is a complete red herring to attempt to get feminists to deal with the problems in gay male porn, when it is already being addressed better by the gay community than straight porn is being dealt with by its users. Straight porn is obviously a bigger problem, both numerically and in terms of a refusal by its users to even vaguely address the ethical issues beyond a handful of people.
