This whole discussion you see above is part of the process of repeating a study. You can't just do exactly what the previous study did and expect all the flaws to magically disappear. You need to first uncover the flaws, and more eyes and collaboration means a higher likelihood that the flaws get found, hence the importance of these discussions. Then you redesign the experiment to fix those flaws, and then you can run it again.

You left it in the parlor

No, what you said was "if you disagree with the science, perhaps you should do your own study".

"Disagree with the science" is a disingenuous oversimplification bordering on nonsensical. People are calling into question the methods of the study, and the conclusions reached by the scientists interpreting the data. All of which can be accomplished with good critical thinking, and all of which is part of the scientific process. We're not "disagreeing with the science". We don't need to repeat this experiment or run our own to be able to point out that it looks like there are flaws in this study - we just need to have good critical thinking skills.

If you disagree with the facts, it is your responsibility to disprove them.

What facts? Are you implying that the content of a scientific study becomes "fact" simply because a scientist publishes it? Because that's wrong, and any published scientist will tell you as much.

That's fair, but I get the feeling that the researchers came up with their conclusion before performing their study, and then interpreted their findings to fit that pre-supposed conclusion. The only thing this study can fairly claim is that some homophobic men may harbor homosexual desires. They've failed to demonstrate any causal linkage between those two attributes, but they're heavily suggesting one exists. Maybe their abstract grossly oversimplifies things, but it seems to extrapolate their findings far beyond any reasonable conclusion in my opinion, and that makes me question their methods and motives more than I normally would. The publication date also raises flags, as the common pervasive sentiment about homosexuality was very different in 1996 than it is today. All of those things combined indicate to me that this study should be carefully considered with plenty of grains of salt at hand.

But to get back on topic a little bit - my original intent was to refute the notion that if someone has a problem with the methodology of a scientific study, then they must perform their own study and present evidence to support a contrary claim. The examples I listed are things it would be reasonable to expect a layman with solid critical thinking skills to point out as potential flaws in this particular study, potential areas to look further into, to confirm whether or not the study is scientifically sound.
