Ummm...That is the statement of an opinion which is different than being "blocked by religious fanatics" or the even more misleading thread title "Fundies Block Cancer Vaccine". The person quoted is stating a pertinent issue, as they are when they say:
"Abstinence is the best way to prevent HPV,"
You might/could possibly/hypothetically take a moment to think about the statement like this:
"Giving the HPV vaccine to young women could be potentially harmful, because they may see it as a licence to engage in premarital sex, which could lead to other, more serious social and/or medical issues down the road. And so we should consider these issues as the approval (and possible mandatory use of) this vaccine is dicussed*."
( * underlined part added as a hypothetical but reasonably possible extension of what this person or other like her might be thinking about when voicing concerns over the effects of this vaccine. )
To which the only apparent response seems to be "You are an immoral, religous nutjob. Shut the fuck up and get the hell out of our public debate, you don't belong."
