To call him a troll could brush aside a few things worth our attention. Disturbingly enough, a statistically significant number of people in the U.S. actually hold viewpoints like these, and unfortunately a few of them occasionally comment on this site. So to call it trolling would be to ignore the depth of the ignorance and repugnance of these peoples' viewpoints, and the menace it poses to society. It's important to recognize these people and bring into the light their extreme right-wing philosophy at every opportunity. You judge a society by how it treats its least — not most — fortunate members.
To be clear, I don't necessarily disagree with you, but I usually hang out on liberal politics, social justice, and assorted culture blogs. In many instances, you get people coming in and saying terrible, hateful, and/or violent things to bloggers, especially when the topic of sexism comes up. In that context, they were still called trolls and for me, the troll label was meant to reinforce my opinion that what they said was Not Okay.
Additionally, based on the initial line ("At the risk of being accused of trolling"), it seemed obvious that the OP KNEW that what they were about to say was terrible and/or offensive. That comment was an attempt to confirm that yes, what they said was bad and they should feel bad.
