Square that statement with your SOURCES contention that there are 15,000 adult bookstores. 20 times would be a number of 500,000 stores renting and selling porn.
And lets use that 25,000 number for the sake of simplicity. Again YOUR sources claim that they outnumber McDonalds by greater than 3-1 is shown to be a lie.
When you have to use lies to support your argument you have no argument.
If video stores that rent and sell hard-core films outnumber adult bookstores by 20 times, and if there are approximately 25,000 such adult bookstores, then simple mathematics says that there are roughly 1,250 adult bookstores. That's a far cry from the 15,000 claimed in your article. Oh, and less than 10% of the number of McDonalds in the country, not the 300+% claimed by your article.
But hey, what's one order of magnitude when you have an agenda to peddle?
