Ned said that liberals are anti-science because "The Left believes that sexual attraction is genetic, even though we have no knowledge of any genes that determine sexual attraction."
I think a fair interpretation of that is that liberals have no reasonable scientific basis for thinking that any part of sexual attraction is genetic (Hence they are anti-science). You even concede that there are likely "biological factors", which presumably arise from genetics.
So are you saying that Ned thinks liberals are anti-science because they believe sexual attraction is genetic, when in reality is just "biological"? Is that really the cornerstone of that particular debate?
"Sexual attraction is genetic".
"No it isn't. It's biological, but not genetic".
"As a liberal, I reject your science!"
