&gt; There is no way to screen for pedophilia unless the prospective parents are already registered offenders.

Well no shit, but you also can't screen them for being mass murderers if they haven't been caught, or screen them from literally anything that they haven't been caught doing wrong.

But you can do psychological testing. 

&gt;The only way to reduce the chance of abuse is by taking into account various risk factors, of which homosexuality is a major one as evinced by the statistics above.

I get that it's a risk factor, though the bias in that source is as you said questionable (plus it has a small sample size).

My point isn't that it isn't a risk factor. It's that it's immoral and irresponsible to discriminate against people based on their inherent characteristics, including sexuality, when the vast majority of those people are not criminals.

Why should 500 gay couples for example not be able to adopt, especially in the USA where a lot of kids struggle to find good homes in the first place (often going to a lower quality home by process of elimination or staying in foster care perpetually), because 1 of them might end up being a child molester? 

Because we should minimize the risk of harm and crime, no matter the cost? 

Even if that means mass discrimination against the vast majority of people based on their inherent characteristics, just to catch a small minority of deviants or criminals?

I'm not sure I think that's an acceptable way of going about it.
