My point was that you can't take a statistic like "10% or 25% of people are gay" and apply it to any subgroup of a population. With that silly logic you can say "1% of the country is Muslim, therefore 1% of Mafia members are Muslim." Which is of course ridiculous.
I can't? Why not? I said all along it's an assumption. BTW, religion is a choice, so already you're comparing apples to oranges.
